| 摘 要： | 在较低的温度下用燃烧合成法快速合成了 Eu2 ,Dy3 掺杂的SrAl2O4长余辉磷光体发光材料.研究了P2O5,CaF2,H3BO3,NaF 几种添加剂对SrAl2O4:(Eu,Dy)粉体发光性能的影响.结果发现:H3BO3和P2O5的添加有利于改善磷光体的发光性能,而在配料中加入CaF2和NaF,磷光体发光效率降低.随着这几种添加剂的加入,SrAl2O4:(Eu,Dy)磷光体材料发射光谱的主发射峰不同程度的出现蓝移.根据实验结果分析了添加剂的作用机理. |

| Abstract: | Strontium aluminate co-doped with Eu2+,Dy3+phosphor powders were rapidly prepared at lower temperatures by combus-tion synthesis.The influence of P2O5,CaF2,H3BO3 and NaF additives on the luminescence properties of SrAl2O4:(Eu,Dy)phosphors was studied.The results indicate that the luminescence properties of SrAl2O4:(Eu,Dy)phosphors are improved by doping of the H3BO3 and P2O5,but suppressed by doping of CaF2 and NaF.The main emission peaks on the emission spectra doped with the addi-tives tend to blue shift compared to that without additives.According to the results,the mechanism of the additives in phosphors was analyzed. |
