The spectral properties of UO22+ silicate glasses are investigated experimentally. The absorption spectra, fluorescent spectra,fluorescent lifetime -stimulated emission section ? and radiative quantum efficiency 77 of UO22+ silicate glasses are measured. The dependence of radiative and nonradiative transition probability on the temperature is discussed, and the curve of concentration quench and temperature quench is given. The results indicate that glass is a good host for UO22+. The lasing of UO2+2 dope in glass is prospootivo.
