摘要: 采用熔融晶化法制备了主晶相为SrF2的Er3+-Yb3+共掺透明氟氧化物玻璃陶瓷,利用DSC、XRD、SEM、UV-Vis-NIR和荧光光谱对样品的结构、形貌、发光性能进行了测试与表征。研究表明:该体系玻璃最佳热处理温度为620℃,最佳热处理时间为2 h,并讨论了Yb3+不同掺杂浓度对Er3+-Yb3+共掺玻璃陶瓷样品上转换发光性能的影响,确定Er3+-Yb3+最佳掺杂浓度比为1:7,同时观察到了明亮的绿光(522,540 nm)和较弱的红光(656 nm),对Er3+和Yb3+之间的能量传递过程进行了讨论。

Abstract: Er3+-Yb3+ co-doped transparent oxyfluoride glass ceramics containing SrF2 crystals were successfully synthesized using a high temperature melting quenching method. The structure, morphology and luminescent properties of the samples were measured and characterized by DSC, XRD, SEM and fluorescence spectra. The results show that the optimum heat treatment temperature is 620℃, and the optimum heat treatment tine is 2 h. The effect of Er3+-Yb3+ co-doped glass ceramics with different doping concentrations of Yb3+ on the up-conversion luminescence properties was discussed. The optimum doping concentration ratio of Er3+-Yb3+ is 1:7. Bright green light (522, 540 nm) and weak red light (656 nm) were observed in the luminescence spectra. The energy transfer process between Er3+ and Yb3+ was discussed.
Keywords: SrF2  glass ceramics  Er3+-Yb3+ co-doped  up-conversion
