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) ...
