  • Luminescence of ZnGa2Î4 AND ZnAl2Î4 spinels doped with Eu3+AND Tb3+ ions 
    RUSU, E.; URSAKI, V.; NOVITSCHI, G.; BURLACU, A.; PETRENKO, P.; KULIUK, L. (I. I. Mechnikov National University, Odessa, 2008)
    Spinel type mono-phase the ZnGa2O4 and ZnAl2O4 compounds doped with Eu3+ and Tb3+ ions were obtained using two methods: solid phase reactions and deposition from chemical solutions. The luminescent analysis of the materials ...
  • The luminescent properties of a ZnGa2O4 spinel doped with Eu 3+ and Er3+ ions 
    VASILE, M.; VLAZAN, P.; SFIRLOAGA, P.; GROZESCU, I.; AVRAM, N. M.; RUSU, E. (IOP Publishing, 2009)
    Nanophosphor of ZnGa2O4:Eu3+ and Er3+ were synthesized by the hydrothermal method. ZnGa2O4 is an intrinsic blue light emitter with a wavelength peak of approximately 608 nm depending on the gallium ratio. A luminescent ...
  • Optical activity induced by rare-earth ions in As2S3 glasses and KCl crystals 
    SYRBU, N.; ZALAMAI, V.; CULEAC, I.; IOVU, M.; TIRON, A. V.; BERIL, S. I.; STAMOV, I. G. (Elservier, 2019)
    Optical transmission spectra of As2S3 glass-like plates and nanolayers, undoped and doped with Sm and Pr ions have been investigated. The spectral dependences of the refractive index and glass transmission spectra, registered ...
