稀土氧化钕对铝酸盐长余辉发光材料性能的影响

Research on SrAl_2O_4∶Eu^(2+) , Dy^(3+) Long Phosphorescent Phosphor

制备了SrAl2 O4 ∶Eu2 + ,Nd3+ 和SrAl2 O4 ∶Eu2 + ,Dy3+ ,Nd3+ 长余辉材料 ,研究了所合成的材料在不同波段紫外光激发条件下的发光光谱和激发光谱的差异和Eu2 + ,Dy3+ ,Nd3+ 的摩尔掺杂浓度对材料的余辉性能的影响等。

The Sr4Al 14 O 25 ∶Eu 2+ , Nd 3+ and Sr 4Al 14 O 25 ∶Eu 2+ , Nd 3+ , Dy 3 systems were synthesized, the differences in the emission spectra and the excitation spectra of Sr 4Al 14 O 25 ∶Eu 2+ , Dy 3+ at different excitation conditions were discussed. This paper also deals with the effects of Eu 2+ , Dy 3+ and Nd 3+ ratio on long phosphorescence materials.
