%X xBi2O3-50B2O3-(50-x)BaO glasses are prepared by melting method. Their infrared luminescence spectra, fluorescence decay curves and Raman scattering spectra are measured. No obvious near-infrared (NIR) luminescence is observed in 50Bi2O3-50B2O3 glass under 808 nm laser diode (LD) pumping. Adding BaO, broadband NIR luminescences are observed in 40Bi2O3-50B2O3-10BaO glass, 45Bi2O3-50B2O3-5BaO glass and 49Bi2O3-50B2O3-1BaO glass. With the increase of BaO concentration, no obvious NIR luminescences are observed in 30Bi2O3-50B2O3-20BaO glass, 20Bi2O3-50B2O3-30BaO glass and 10Bi2O3-50B2O3-40BaO glass. The NIR emissions with several emission peaks appear in 0.5Bi2O3-50B2O3-50BaO glass and 1Bi2O3-50B2O3-50BaO glass. The mechanism for the emission is investigated preliminarily.
