The SiO2-B2O3-Al2O3-Gd2O3 system based samples doping with rare earth Ce3+ ions (cations) are synthesized by high-temperature melting method. The effects on their density, transmission and scintillating properties are investigated. The results indicate that all the samples, especially those that have high densities, have good physical properties. The emission peak wavelengths of all samples excited by X-ray are at 390 nm. Increasing the concentrations of Ce3 + and Gd3+ ions has a positive effect on luminescence properties. However, when the concentration of Ce3+ ions arrives at 1 mol%, with the increase of the concentration of Ce3+, the emission peak decreases. When Gd3+ ions concentration reaches a certain value scintillating properties decreases with Gd3+ ion concentration increasing. The X-ray-induced luminescence intensity of the sample of SBAG4 is about 90% that of BGO crystal. Gd3+ ions can sensitize the luminescence of Ce3+, the best concentration of Ce3+ ions is 1 mol% and the best concentration of Gd3+ ions is 15 mol%. These samples are attractive for some physical applications.
