| 摘 要： | Effect of Gd2O3 addition on optical properties of 27.5 Li2O-72.5 B2O3 glass systems was studied. Density, differential thermal analysis(DTA), optical absorption spectra and luminescence technique were used to characterize the prepared glasses. Emission spectra showed two band 6P7/2→8S7/2(311.5 nm) and 6P5/2→8S7/2(305 nm) under the excitation of 274 nm. The intense emission at 311.5 nm suggested that these glasses could be useful as source of narrowband UV light.
