摘要:

采用高温固相法制备出初始发光亮度高、余辉时间长的SrAl2O4:Eu 2+,Dy 3+长余辉发光材料,对其发光性能进行了研究。以初始发光亮度为响应指标,采用响应面分析法确定了制备初始发光亮度高的铝酸锶长余辉发光材料最优工艺条件:烧结温度为1 306.74 ℃、激活剂物质的量分数为0.03%,辅助激活剂物质的量分数为0.03%,助熔剂物质的量分数为0.28%,在此条件下得到的初始亮度实际测量值为2 991 mcd/m 2,与理论预测值2 998.71 mcd/m 2基本吻合。该研究可为制备初始发光亮度高、余辉时间长的铝酸锶长余辉发光材料提供参考。

Abstract:

SrAl2O4:Eu 2+,Dy 3+ long afterglow luminescent materials with high initial luminous brightness and long afterglow time were prepared by high temperature solid phase method,and their luminescent properties were studied.Taking the initial luminous brightness as the response index,the response surface analysis method was used to determine the optimal process conditions for preparing strontium aluminate long afterglow luminescent materials with high initial luminous brightness:the sintering temperature of 1 306.74 ℃,the activator amount-of-substance fraction of 0.03%,the auxiliary activator amount-of-substance fraction of 0.03% and the flux amount-of-substance fraction of 0.28%.Under the conditions,the actual measured value of initial luminous brightness was 2 991 mcd/m 2,which was basically consistent with the theoretical predicted value of 2 998.71 mcd/m 2.This study can provide reference for the preparation of strontium aluminate long afterglow luminescent materials with high initial luminous brightness.
