| 摘 要： | 以马来酸酐(MA)和吲哚啉螺苯并吡喃(SP)为原料,在SrAl2O4∶Eu2+,Dy3+(SAO-ED)发光粉的表面进行复合包覆制备MA-SP-SAO-ED复合发光粉,探讨MA与SP的质量比、MA和SP的加入顺序对复合发光粉性能的影响,并用扫描电镜表征复合发光粉的表面涂层。结果表明,当MA和SP同时加入SAO-ED二氯甲烷溶液中,总加入量为SAO-ED发光粉质量的10%,且MA与SP的质量比为6∶1时,复合发光粉具有较好的耐水、光致发光和光致变色等性能;在SAO-ED发光粉表面包覆了均匀致密涂层。

| Abstract: | MA-SP-SAO-ED composite phosphors were prepared with two organic materials maleic anhydride(MA) and indoline spiropyrans(SP) directly coated on the surface of SrAl2O4∶Eu2+,Dy3+(SAO-ED) phosphors.The effect of the mass ratio and adding order of MA and SP on the properties of MA-SP-SAO-ED composite phosphors was discussed.The coating of the composite phosphors was characterized by SEM.The results show that the coated SAO-ED phosphors have higher water resistance and photoluminescence and photochromic properties when the mass ratio of MA and SP is 6∶1 and the total mass fraction is 10%.A homogenous and compact coating layer is formed. |
