    Thin films (1-10 μm thickness) of nanocomposites (NC) based on organic coordinated compound (OCC) Eu(TTA)2(Ph3PO)2NO3 (where TTA is thenoyltrifluoroacetonate (C8H5F3O2S), Ph3PO - triphenylphosphine (C6H5PO) and polymer – ...
  • Effective Transfer of UV Energy to Red Luminescence in the Nanocomposites Polymer/Eu Coordination Compounds 
    VERLAN, V. I.; IOVU, M. S.; CULEAC, I.; BORDIAN, O.; ZUBAREVA, V. E.; NISTOR, Iu. (Tehnica UTM, 2015)
    Nanocomposites (NCs) thin films based on oligomer poly-N-epoxypropylcarbazole (PEPC) and organic coordinated compounds (OCC) have been obtained by chemical methods. Absorption threshold for samples with different concentrations ...
  • Energy Transfer in Organic Luminophore Nanocomposites 
    VERLAN, V.; ANDRIESH, A. M.; CULEAC, I.; POPUSHOI, A.; DRAGALIN, G.; BARBĂ, N.; BUZURNIUC, S.; MALAHOV, L. (Technical University of Moldova, 2011)
    New light-emitting layers of nanocomposites on polymer base have been obtained. As polymeric matrices the poly-N-vinylpirrolidone has been used. As organic luminophore matertials new compound from izotiocianatopropenone ...
  • Nanocomposites and Polymer Thin Films: from Gas Phase Synthesis to Functional Applications 
    SCHRÖDER, Stefan; VAHL, Alexander; VEZIROGLU, Salih; LUPAN, Oleg; AKTAS, Cenk; STRUNSKUS, Thomas; FAUPEL, Franz (Universitatea Tehnică a Moldovei, 2023)
    Among the functional nanocomposites, our group has focused on highly filled particulate metal-dielectric nanocomposites films due to their unique functional properties with hosts of applications. To explore collective ...
  • Nanolayers of the Au0x0SnO2 nanocomposite synthesized by successive ionic layer deposition method 
    TOLSTOY, V.; GULINA, L.; KOROTCENKOV, G. (Technical University of Moldova, 2005)
    We studied possibilities of SILD (successive ionic layer deposition) technology for depositing nanocomposite Au0xSnO2 nanolayers. This new method of layer deposition is of high interest, because of the method’s simplicity, ...
  • Nanowires of Silicon Carbide and 3D SiC/C Nanocomposites With Inverse Opal Structure

    Synthesis, morphology, structural and optical characteristics of SiC NWs and SiC/C nanocomposites with an inverse opal lattice have been investigated. The samples were prepared by carbothermal reduction of silica (SiC NWs) ...
  • Optical Properties and Photoinduced Anisotropy of PEPC-co-SY3 Nanocomposite 
    LOŞMANSCHII, Constantin; ACHIMOVA, Elena; ABASKIN, Vladimir; MESALCHIN, Alexei; PRISACAR, Alexandr; BOTNARI, Vladislav (Springer Nature Switzerland, 2023)
    In the present work, the optical properties of the PEPC-co-SY3 nanocomposite doped with gold nanoparticles are brought to light. The samples were prepared with 3 different concentrations of Au as well as a control sample ...
  • Preparation and optical characterization of the new polymer nanocomposites 
    ANDRIESH, A.; BIVOL, V.; BUZURNIUC, S.; MESHALCHIN, A.; ROBU, S.; VERLAN, V. (Technical University of Moldova, 2005)
    The polymer nanocomposites consisting of polyvinylalcohol (PVA) and chalcogenide non-crystalline semiconductors (ChNS) as arsenic selenide (As2Se3) and arsenic sulfide (As2S3) were obtained. The optical absorption was ...
