  • Characterization of high refractive amorphous (As4S3Se3)1-x:Snx chalcogenide glasses 
    IASENIUC, O. V.; IOVU, M. S.; COLOMEICO, E. P.; SHEPEL, D. F.; MESHALKIN, A. (Technical University of Moldova, 2012)
    The transmission spectra of bulk and thin films of (As4S3Se3)1-x:Snx in the visible and infrared (IR) regions were investigated. Doping of As4S3Se3 chalcogenide glass with Sn impurities essentially reduce the absorption ...
  • Influence of rare-earth impurities on optical properties of As2S3 glasses and KCl crystals 
    TIRON, A. V.; ZALAMAI, V. V.; IOVU, M. S.; SYRBU, N. N. (Tehnica UTM, 2018)
    Optical transmission spectra of As2S3 glass-like plates and nanolayers, undoped and doped with Sm2+, Sm3+, Dy3+, Pr3+, and Mn3+ ions have been investigated. The spectral dependences of the refractive index and glass ...
  • Luminescence of nanocomposites with different coordination of Eu+3 ions and polymers 
    VERLAN, V. I.; IOVU, M. S.; ANDRIESH, A. M.; CULEAC, I.; TURTA, C. I.; ZUBAREVA, V. E. (Technical University of Moldova, 2012)
    Thin films (1-3 μm thickness) of nanocomposites (NCs) based on organic compounds with Eu3+ ions (Eu(TTA)3H2O, Eu(TTA)3Phen, Eu(DBM)3Phen and Eu(TTA)2(Ph3PO)2NO3) and polymer polyvinylpyrrolidone (PVP) or copolymer ...
  • Physical and optical properties of amorphous (As2(Sb2)Se3)1-X:SnX thin films 
    IOVU, M. S.; HAREA, D. V.; COLOMEICO, E. P.; HAREA, E.; COJOCARU, I. A. (Technical University of Moldova, 2012)
    The mechanical properties (the hardness H), the morphology, the 119Sn Mossbauer spectroscopy, and the Temperature Modulated Differential Scanning Calorimetry (MDSC) of amorphous (As2Se3)1-x:Snx and (Sb2Se3)1-x:Snx bulk ...
  • Raman scattering of Ge-As-Se thin films 
    IASENIUC, O. V.; IOVU, M. S.; GHIULNARE, A.; MESTERCA, R.; JDERU, A.; ENACHESCU, M. (Tehnica UTM, 2018)
    Raman and infrared spectroscopy are efficient methods for obtaining information on the local structure of the disordered material, especially when the composition is varied. In particular, Micro-Raman spectroscopy have ...
