    PINTEA, V.; ARAMA, E.; GHEORGHITSA, E.; MACIUGA, A.; ZHITAR, V. (Academy of Sciences of Moldova, 2014)
    This study presents the results of investigations on the conductivity and irradiation stability of single crystals ZnIn2S4 in a wide range of incident electron energies (3075 keV) and respective doses (10141020 cm2). The ...
  • Photocatalytic indium-tantalum-oxide and its photoluminescence 
    KANTSER, V.; MUNTEAN, S.; ZHITAR, V.; VOLODINA, G.; KAPLIN, V.; URSAKI, V. (Institutul de Inginerie Electronică şi Nanotehnologii "D. Ghiţu" al AŞM, 2003)
    Both bulk ceramic and powder like samples In0,9Ni0,1TaO4 photocatalytic semiconductor oxides have been obtained by the method of solid phase reactions. The photocatalytic activity on water splitting has been investigated ...
  • Photoluminescence in ZnGa2O4 
    ZHITAR, V.; URSAKI, Veacheslav; ARAMĂ, Efim; SHEMYAKOVA, Tatiana; MUNTEAN, Ştefan (Institutul de Inginerie Electronică şi Nanotehnologii "D. Ghiţu" al AŞM, 2005)
    ZnGa2O4 compound has been prepared by a simple method of ceramic sintering. Its photoluminescence (PL) spectra have been studied using laser beam excitation (l = 334 nm) at 295 and 10 K. A blue-green long wavelength radiation ...
  • Preparation and photoluminescence of ZnGa2O4:Co 
    ZHITAR, V.; URSAKI, Veacheslav; VOLODINA, Galina; MUNTEAN, Ştefan; SHEMYAKOVA, Tatiana (Institutul de Inginerie Electronică şi Nanotehnologii "D. Ghiţu" al AŞM, 2007)
    Ceramic samples of ZnGa2O4 doped with Co have been prepared. Their photoluminescence = 351 nm) and various temperatures (10 – 300 K)spectra measured at laser excitation (λ contain a wide band, centered at 2.8 eV (10 K) ...
  • Specific features of radiative recombination spectra of ZnIn2S4 single crystals 
    ARAMA, E.; GHEORGHITA, E.; PINTEA, V.; ZHITAR, V. (Academy of Sciences of Moldova, 2013)
    Radiative recombination spectra of Mn-doped zinc tioindat single crystals have been analyzed in the work. The emission spectra interval close to its maximum (1.91 ± 0.2 eV) contains a number of special features which were ...
