AbstractThe 2Bi2O3-3GeO2/SiO2glass samples have been prepared by the conventional melt quenching technique. XRD patterns, absorption spectra, excitation-emission spectra and Raman measurements were utilized to characterize the synthesized glasses. When substitute SiO2for GeO2, the 0.4Bi2O3-(0.4-0.1)GeO2-(0.2–0.5)SiO2glasses exhibit strong emission centered at about 475 nm (under 300 nm excitation), and the decay constants are within the scope of 20–40 ns. W doping into 2Bi2O3-3SiO2glass could increase the emission intensity of 470 nm, and the W-doped 2Bi2O3-3SiO2glass has shown another emission at about 433 nm with much shorter decay time (near 10 ns). The 2Bi2O3-3GeO2/SiO2glass system could be the possible candidate for scintillator in high energy physics applications. © 2017 Elsevier Ltd
