摘要
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.关键词
