Abstract

Photoluminescence and scintillation properties of 0.1%, 0.5%, 1.0%, and 5.0% Er:CaHfO₃ single crystals were synthesized and evaluated. The photoluminescence and scintillation spectra showed several emission peaks originating from the 4f–4f transitions of Er³⁺ in visible and near-infrared regions. Dose-rate-response of 0.5%, 1.0%, and 5.0% Er:CaHfO₃ samples showed an excellent linear relationship between dose rate and output signal intensity across the range of 0.0025–51 Gy/h. Based on the results, the 1.0% Er:CaHfO₃ sample exhibited the best performance among all the Er:CaHfO₃ samples.

掺铒CaHfO3单晶闪烁体发射近红外光子的研制

合成了0.1%、0.5%、1.0%和5.0% Er:CaHfO3单晶，并对其光致发光和闪烁性能进行了评价。光致发光和闪烁光谱显示Er3+在可见光和近红外区域的4f-4f跃迁产生了多个发射峰。在0.5%、1.0%和5.0%的Er:CaHfO3样品中，剂量率与输出信号强度在0.0025-51 Gy/h范围内呈良好的线性关系。结果表明，1.0% Er:CaHfO3样品在所有Er:CaHfO3样品中表现出最好的性能。
