The rare earth Ce3 ion doped SiO2-B2O3-BaO-Gd2O3 system is synthesized by high-temperature melting method. The density, transmission, excitation spectra and scintillating properties of the glasses are investigated. The results indicate that all the samples have good physical and scintillating properties. The emission peak wavelength of all samples is 390 nm under X-ray radiation. Gd3 ions have a negative impact on scintillating properties when its concentration reaches a certain level. Gd3 ions sensitize the luminescence of Ce3 ions, and the ideal concentration is 15 mol% for Gd3 ions. Also the decay characteristics of Ce3 and Gd3 ions are investigated. These samples have potential practical applications in high energy physics.
