| Rezumat | ||||||
The absorption and radiation spectra of Ga-La-S-O glasses with fixed cation ratio Ga/La=0.7/0.3 and two oxygen content 0.65 Wt % and 2.95 Wt % were studied for two Pr3+ doping levels of 0.1 and 1.0 Wt %. Presence of oxygen induces blue shift of the fundamental absorption edge and results in lowering of the low-energy components of the Pr3+ absorption bands. The glasses show bright luminescence due to Pr3+ ion emission similar to that in other glasses. The effect of oxygen on the luminescence spectra is determined by decreasing of host glass self-absorption of the short-wavelength bands, which became visible with oxide content growing. |
