  • Light trapping and plasmonic enhancement in silicon, dye-sensitized and
           titania solar cells

    • Authors: Hong Nhung Tran; Van Hieu Nguyen, Bich Ha Nguyen Dinh Lam Vu
      First page: 013001
      Abstract: The efficiency of a solar cell depends on both the quality of its semiconductor active layer, as well as on the presence of other dielectric and metallic structural components which improve light trapping and exploit plasmonic enhancement. The purpose of this work is to review the results of recent research on light trapping and plasmonic enhancement in three types of solar cells: thin-film silicon solar cells, dye-sensitized solar cells and solid-state titania solar cells. The results of a study on modeling and the design of light trapping components in solar cells are also presented.

  • Advances in graphene-based optoelectronics, plasmonics and photonics

    • Authors: Bich Ha Nguyen; Van Hieu Nguyen
      First page: 013002
      Abstract: Since the early works on graphene it has been remarked that graphene is a marvelous electronic material. Soon after its discovery, graphene was efficiently utilized in the fabrication of optoelectronic, plasmonic and photonic devices, including graphene-based Schottky junction solar cells. The present work is a review of the progress in the experimental research on graphene-based optoelectronics, plasmonics and photonics, with the emphasis on recent advances. The main graphene-based optoelectronic devices presented in this review are photodetectors and modulators. In the area of graphene-based plasmonics, a review of the plasmonic nanostructures enhancing or tuning graphene-light interaction, as well as of graphene plasmons is presented. In the area of graphene-based photonics, we report progress on fabrication of different types of graphene quantum dots as well as functionalized graphene and graphene oxide, the research on the photoluminescence and fluorescence of graphene nano...

  • Targeted drug delivery nanosystems based on copolymer
           poly(lactide)-tocopheryl polyethylene glycol succinate for cancer
           treatment

    • Authors: Phuong Thu Ha; Hoai Nam Nguyen, Hai Doan Do, Quoc Thong Phan, Minh Nguyet Tran Thi, Xuan Phuc Nguyen, My Nhung Hoang Thi, Mai Huong Le, Linh Toan Nguyen, Thuc Quang Bui Van Hieu Phan

      Abstract: Along with the development of nanotechnology, drug delivery nanosystems (DDNSs) have attracted a great deal of concern among scientists over the world, especially in cancer treatment. DDNSs not only improve water solubility of anticancer drugs but also increase therapeutic efficacy and minimize the side effects of treatment methods through targeting mechanisms including passive and active targeting. Passive targeting is based on the nano-size of drug delivery systems while active targeting is based on the specific bindings between targeting ligands attached on the drug delivery systems and the unique receptors on the cancer cell surface. In this article we present some of our results in the synthesis and testing of DDNSs prepared from copolymer poly(lactide)-tocopheryl polyethylene glycol succinate (PLA-TPGS), which carry anticancer drugs including curcumin, paclitaxel and doxorubicin. In order to increase the targeting effect to cancer cells, active targeting ligand folate was ...

  • Synthesis of nanoparticles composed of silver and silver chloride for a
           plasmonic photocatalyst using an extract from a weed Solidago
           altissima (goldenrod)

    • Authors: Vemu Anil Kumar; Takashi Uchida, Toru Mizuki, Yoshikata Nakajima, Yoshihiro Katsube, Tatsuro Hanajiri Toru Maekawa
      First page: 015002
      Abstract: Phytosynthesis of nanomaterials is advantageous since it is economical, ecofriendly, and simple, and, what is more, in the synthetic protocols, nontoxic chemicals and biocompatible materials are used. Here, a green synthetic methodology of nanoparticles (NPs) composed of silver (Ag) and silver chloride (AgCl) NPs is developed using a leaf extract of Solidago altissima as a reducing agent for the first time. Utilization of a terrestrial weed for the synthesis of Ag and AgCl NPs is a novel environmentally friendly approach considering that no toxic chemicals, external halide source, or elaborate experimental procedures are included in the process. The optical properties and elemental compositions of as-synthesized Ag and AgCl NPs are well characterized, and the degradation of an organic dye, i.e., rhodamine B (RhB), is investigated using the Ag and AgCl NPs. We find that degradation of RhB is effectively achieved thanks to both surface plasmon resonance and semiconductor pr...

  • Progress in the research and development of photonic structure devices

    • Authors: Van Hoi Pham; Huy Bui, Thuy Van Nguyen, The Anh Nguyen, Thanh Son Pham, Van Dai Pham, Thi Cham Tran, Thu Trang Hoang Quang Minh Ngo
      First page: 015003
      Abstract: In this paper we review the results of the research and development of photonic structure devices performed in the Institute of Materials Science in the period from 2010–2015. We have developed a configuration of 1D photonic crystal (PC) microcavities based on porous silicon (PS) layers and applied them to optical sensing devices that can be used for the determination of organic content with a very low concentration in different liquid environments. Various important scientific and technological applications of photonic devices such as the ultralow power operation of microcavity lasers, the inhibition of spontaneous emissions and the manipulation of light amplification by combining the surface plasmonic effect and the microcavity are expected. We developed new kinds of photonic structures for optical filters based on guided-mode resonances in coupled slab waveguide gratings, which have great potential for application in fiber-optic communication and optical sensors.

  • ZnO nanoplates surfaced-decorated by WO 3 nanorods for NH 3 gas sensing
           application

    • Authors: Dac Dien Nguyen; Duc Tho Do, Xuan Hien Vu, Duc Vuong Dang Duc Chien Nguyen
      First page: 015004
      Abstract: Zinc oxide (ZnO) nanoplates and tungsten trioxide (WO 3 ) nanorods were synthesized by hydrothermal treatment from zinc nitrate/potassium hydroxide and sodium tungstate/hydrochloric acid, respectively. The structure, morphology and compositions of the as-prepared WO 3 /ZnO nano-composites were characterized by x-ray diffraction, field emission scanning electron microscopy and energy dispersive spectroscopy. The obtained ZnO nanoplates have regular shape, single-crystal wurtzite structure with the thickness of 40 nm and 200 versus 400 nm in lateral dimensions. The WO 3 nanorods possess the average diameter of 20 nm and the length of approximately 120 nm which were distributed on the surfaces of ZnO nanoplates. The WO 3 /ZnO nano-composites were prepared by grinding WO 3 nanorods powder with ZnO nanoplates powder in various weight ratios (1:2, 1:1 and 2:1). The NH 3 gas sensing properties of WO 3 /ZnO nano-composite...

  • Comparing plasmonic electrodes prepared by electron-beam lithography and
           electrochemical reduction of an Au (iii) salt: application in active
           plasmonic devices

    • Authors: Van-Quynh Nguyen; Delphine Schaming, Pascal Martin Jean-Christophe Lacroix
      First page: 015005
      Abstract: This work describes two different methods for obtaining electrodes covered with gold nanoparticles: electron-beam lithography and electroreduction of an Au ( iii ) salt by chronoamperometry. Localized surface plasmon resonances of these different electrodes have been compared. In a second step, these plasmonic AuNP electrodes were covered with an ultrathin organic film of bisthienylbenzene which displays a reversible voltage-dependent switch between conducting and insulating states. The effect of this conductance switch on the plasmonic properties of the AuNPs has been studied.

  • Synthesis of gold nanorods with a longitudinal surface plasmon resonance
           peak of around 1250 nm

    • Authors: Thi Nhat Hang Nguyen; Thi Le Trinh Nguyen, Thi Thanh Tuyen Luong, Canh Minh Thang Nguyen Thi Phuong Phong Nguyen
      First page: 015006
      Abstract: We prepared gold nanorods and joined them to chemicals such as tetrachloauric (III) acid trihydrate, silver nitrate, hydroquinone, hexadecyltrimethylammonium bromide, sodium hydroxide and sodium borohydride using the seed-mediated method. The combination of hydroquinone, with or without salicylic acid, influences the size of the gold nanorods, and this is demonstrated by the results of TEM images, UV–vis spectra and the value of the longitudinal surface plasmon resonance peak with respect to the UV–vis spectra. By changing the Ag + ion and hydroquinone concentration and the combination of hydroquinone and salicylic acid, the size of the gold nanorods can be controlled and this is manifested by longitudinal surface plasmon resonance peaks forming between 875 and 1278 nm. In particular, sample E2 achieved a  longitudinal surface plasmon peak at 1273 nm and an aspect ratio of more than 10 by modifying the hydroquinone to 2.5 mM and salicylic acid to 0.5 mM concentration i...

  • DRIE process optimization to fabricate vertical silicon nanowires using
           gold nanoparticles as masks

    • Authors: Thanh Tung Bui; Hoan Phuc Tu Mau Chien Dang
      First page: 045016
      Abstract: Silicon nanowires have applications in various fields, e.g. vertical transistors, chemical or biological sensors, energy conversion, and storage devices. So far they have typically been obtained by bottom-up methods such as vapor–liquid–solid (VLS) synthesis, starting from metal nanoparticles. In this study, silicon nanowires are fabricated by dry reactive-ion etching using gold nanoparticles as a mask. Starting with the Bosch process, the cycle of SF 6 plasma etching and C 4 F 8 plasma deposition was optimized to control the quality of the resulting silicon nanowires.

  • Synthesis and spectroscopic characterization of gold nanobipyramids
           prepared by a chemical reduction method

    • Authors: Vo Ke Thanh Ngo; Trong Phat Huynh, Dang Giang Nguyen, Hoang Phuong Uyen Nguyen, Quang Vinh Lam Thanh Dat Huynh
      First page: 045017
      Abstract: Gold nanobipyramids (NBPs) have attracted much attention because they have potential for applications in smart sensing devices, such as medical diagnostic equippments. This is due to the fact that they show more advantageous plasmonic properties than other gold nanostructures. We describe a chemical reduction method for synthesizing NBPs using conventional heating with ascorbic acid reduction and cetyltrimethylamonium bromide (CTAB) + AgNO 3 as capping agents. The product was characterized by ultraviolet–visible spectroscopy (UV–vis), Fourier transmission infrared spectroscopy (FTIR), transmission electron microscopy (TEM), x-ray powder diffraction (XRD). The results showed that gold nanoparticles were formed with bipyramid shape (tip-to-tip distance of 88.4 ± 9.4 nm and base length of 29.9 ± 3.2 nm) and face-centered-cubic crystalline structure. Optimum parameters for preparation of NBPs are also found.
