中文摘要：

用微波法合成了SrAl2O4：Eu2＋,RE3＋（RE3＋=Er3＋,Dy3＋,Ho3＋,Nd3＋,Sm3＋,Ce3＋,Gd3＋）系列长余辉发光材料。XRD结果表明：所得发光材料为α-SrAl2O4。激发光谱、发射光谱结果表明：RE3＋的掺杂不改变材料的主发射峰位置,在室温下观察到了SrAl2O4：Eu2＋,RE3＋（RE3＋=Er3＋,Dy3＋,Ho3＋,Nd3＋）的绿色上转换发光。余辉衰减曲线和热释光谱结果显示：余辉的初始亮度最高,时间最长,热释峰的温度最接近室温的是SrAl2O4：Eu2＋,Nd3＋。

英文摘要：

Long persistent phosphorescence SrAl2O4 ： Eu2 ＋ , RE3 ＋ （ RE3 ＋ = Er3＋, Dy3 ＋ , Ho3 ＋, Nd3 ＋, Sm3＋ ,Ce3 ＋ , Gd3＋ ）was synthesized by microwave radiation method. XRD analysis showed that crystal structure of phosphor is α phase SrAl2O4. The results of the spectroscopic analysis for the excitation and emission spectrum indicate that the main peak of luminescence spectra does not change after doping the RE3＋ ions and SrAl2O4 ：Eu2＋ ,RE3＋ （RE3＋ = Er3＋ ,Dy3＋ ,Ho3＋ ,Nd3. ） show strong green up-conversion emission. The decay curve of fluorescence and the spectrum of thermoluminscent showed SrAl2O4 ： Eu2＋ , Nd3＋ have the merits of the highest initial luminescent intensity, the longest duration time, and the temperature of heating releasing peak closest to the room temperature.
