Abstract制备了发光性能良好的SrAl_2O_4:Eu~(2+)材料,对其激发光谱、发射光谱和长余辉曲线进行了测试与分析讨论,结果表明长余辉衰减符合函数L=ct~(-alpha)(alpha=0.754)形式。讨论了SrAl_2O_4:Eu~(2+)材料的长余辉机理,指出长余辉应来自陷阱对空穴的俘获与缓慢释放。发现了SrAl_2O_4:Eu~(2+)材料的力致发光性能并分析了其可能原因。

Other AbstractSrAl_2O_4:Eu~(2+) with optimum luminescence properties was prepared. The excitation spectrum, the emission spectrum and the long decay curve were measured and analyzed. The results showed that the long decay curve had the form L=ct~(-alpha)(alpha=0.754). The long afterglow mechanisms of SrAl_2O_4:Eu~(2+) were also discussed. It must have arisen from the capture and release of the hole by the trap. The stress-induced luminescence was observed here, and possible reasons were suggested.
