| 摘 要： | 实验用有机硅KH570对荧光粉进行二氧化硅包覆以改善其耐水性，在包覆量为3％时得到由致密二氧化硅薄层包覆的产品，铝酸锶的耐水性有很大提高，原样在1．5h内完全水解，而包覆产品在300h内无水解现象，而包覆后对颜料的荧光性能影响很小，荧光强度降低在5％以下，不影响荧光粉的使用。

| Abstract: | The encapsulation on SrAl_2O_4:Eu~(2+),Dy~(3+)phosphors was studied by coating silicane coupling agent - KH570 onto phosphors' surface and turned it into SiO_2 thin film by heating. The measurement results of FL?SEM and TEM showed that the encapsulation film is integrity enough as well as dense. The measurement results of water-resistance and luminescent properties indicated that the encapsulated SrAl_2O_4:Eu~(2+), Dy~(3+) phosphors have better water-resistance performance, and still keep good persistent photoluminescent properties. |
