Luminescence properties of Ce3+- doped borate scintillating glass for new radiation detection material

Highlights: • Ce doped in borate glasses were developed. • Highest emission intensity of CeF₃ was observed at 0.5 mol%. • The strongest emission band of X-rays induced luminescence is around 398 nm. • To the XANES results confirmed all Ce was present as Ce³⁺ and Ce⁴⁺. • The decay times of glass were reported in the nanoseconds order. 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.
