研究加入Dr3+离子后的Ca1-xSrxS:Eu2+，Er3+的荧光激发光谱、发射光谱及余辉时间．结果表明，Ca1-xSrxS:Eu2+，Dy3+，Er3+是一种发光效率高、余辉时间长的红色发光材料．
Fluorescence excitation spectrum, emission spectrum and afterglow time of Ca1-xSrxS: Eu2 +, Er3 + after adding Dr3 + ions were studied. The results show that Ca1-xSrxS: Eu2 +, Dy3 +, Er3 + is a red luminescent material with high luminous efficiency and long afterglow.
