Ca2MgTeO6∶Bi3+,Mn4+材料的发光性能和温度探测
Luminescent Properties and Temperature Sensing of Ca2 MgTeO6∶Bi3+,Mn4+ Phosphors
摘要
Abstract
A series of novel Ca2MgTeO6∶Bi3+,Mn4+ phosphors were successfully prepared using the high-tempera-ture solid-state method.The microstructure,morphology,luminescence properties,and temperature-sensitive prop-erties were characterized.The dual emission centers with different temperature sensitivity of Ca2MgTeO6∶Bi3+,Mn4+ phosphors are derived from the 3P1 →1S0 transition of Bi3+ ions and the 2Eg→4A2g transition of Mn4+ ions,respectively.Since the luminescence centers of Bi3+ and Mn4+ ions vary with temperature,the phosphor's maximum absolute sensi-tivity and relative sensitivity are 0.027 K-1 and 1.83%·K-1 in the 200-500 K range,respectively.At the same time,the luminescence color of Ca2MgTeO6∶Bi3+,Mn4+ changes from orange at 200 K to purple at 500 K.The experimental results show that Ca2MgTeO6∶Bi3+,Mn4+ phosphors can be used as optical materials for temperature detection.关键词
