摘要
制备了ＳｒＡｌ２Ｏ４∶Ｅｕ，Ｄｙ材料。并测得其激发光谱，发射光谱和衰减曲线。首次报道了Ｄｙ的含量与荧光亮度和持续时间的关系，并对ＳｒＡｌ２Ｏ４∶Ｅｕ，Ｄｙ系统的发光机理进行了解释。
SrAl2O4Eu,Dy materials was prepared.The fluorescence spectra,the excitation spectra and the decay curves were measured.The relations between the content of Dy,the light intensity and light-lasting time were first reported in this paper.The explanation of the luminescent mechanism of SrAl2O4Eu,Dy materials was presented.
