Abstract

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 Ф12 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.

Pr3+共掺杂CLLBC: Ce晶体的发光特性及能量传递机理

共掺杂策略是提高发光材料性能的有效途径。在本研究中，采用Bridgman方法成功地生长出了不同浓度的Ce和Pr3+共掺杂CLLBC:Ce晶体。加工晶体样品的尺寸约为Ф12 mm * 6 mm。XRD和XPS表征结果证实了Pr³+掺入CLLBC:Ce晶体主体中。通过荧光光谱、XEL和衰变动力学研究了Pr3+和Ce3+取代量对发光和闪烁性能的影响。观察了Pr3+和Ce3+之间的能量传递，并对闪烁机理进行了全面讨论。结果表明，Pr3+共掺杂显著提高了CLLBC:Ce晶体的发光性能。
