Abstract

A series of glasses composed (Ce3+ and Gd3+) co-doped lithium aluminum borate glasses with composition 25Li2O–5Al2O3-XGd2O3-(69.5-X)B2O3-0.5CeF3 glasses were successfully synthesized by using a conventional melt-quenching technique and characterized through physical, structural and luminescence properties. The optimal doping concentration of CeF3 contents is 0.5 mol% and varying Gd2O3 concentration for studying the combined effect of dual doped glass. Further, the phenomenon of energy transfer from the host glass in luminescence center was observed by x-rays induced luminescence spectra, as well as from Gd3+to Ce3+ ions are confirmed by photoluminescence emission spectra. The strongest emission intensity of Ce3+emission is obtained when the scintillating glass contains 5.0 mol% of Gd2O3 concentration. From the nano-second decay time of glass exhibit a high potential for using as scintillating materials.
