| 摘 要： | 研究了SrAl12O19:Pr3+ 和Y3Al5O12(YAG):Pr3+ 在20K, 77K和300K的真空紫外(VUV)光谱，二者除了表现出Pr3+特有的发射性质外，还产生了一种特殊的发射现象，即自陷激子(STE)发射,并且其随着稀土离子浓度和温度的降低而增强. 还着重讨论了自陷激子对Pr3+发光的影响.

| Abstract: | Spectroscopic properties of SrAl12O19:Pr3+ and Y3Al5O12:Pr3+ have been studied under vacuum ultraviolet excitation at 20, 77 and 300K. Self-trapped exciton(STE) luminescence in these aluminates were observed besides the characteristic emissions of Pr3+. Furthermore, the emission of STE became dominant as the concentration of activators and temperature decreased. The influence of STE on the luminescence of Pr3+ in aluminates was also emphasized. |
