摘要：
A co-doping strategy is an effective approach for enhancing the properties of luminescence materials. In this study, Pr3+ co-doped CLLBC:Ce crystals with varying concentrations of Ce and Pr3+ were successfully grown using the Bridgman method. The dimensions of the machined crystal samples were approximately & Fcy;12 mm * 6 mm. Characterization results of XRD and XPS confirmed the incorporation of Pr3+into the CLLBC:Ce crystal host. The effects of the substitution amount of Pr3+ and Ce3+ on the luminescent properties and scintillation properties were systematically investigated by fluorescence spectroscopy, XEL, and decay kinetics. Energy transfer between Pr3+ and Ce3+ was observed, and the scintillation mechanism was comprehensively discussed. The results demonstrate that Pr3+ co-doping significantly enhances the luminescent properties of CLLBC:Ce crystals.
