摘要:
以异丙醇铝为原材料，采用溶胶凝胶法制备铝溶胶，利用荧光粉在铝溶胶中的异相成核原理在硅酸锶镁表面包覆一层氧化铝膜，并考察了包覆对荧光粉的物相和晶体结构、表面形态、发光性质以及热稳定性的影响，分析了不同包覆量对其余辉性能的影响及热处理温度对荧光粉的影响.结果表明，在荧光粉表面成功包覆了一层均匀、致密且牢固的氧化铝膜层；包覆过程没有改变荧光粉的晶体结构；随着包覆量的增加，样品的余辉初始亮度呈现逐渐下降的趋势，当包覆量为8%时，余辉亮度下降最小，发光强度下降约10%；随着热处理温度的升高，未包覆和包覆样品的余辉亮度逐渐下降，在900 ℃时，未包覆样品的余辉亮度衰减0.24，而包覆样品的余辉亮度衰减约0.1.包覆提高了荧光粉的发光性能.
Abstract:
The aluminum sol was prepared using the aluminium isopropoxide as the starting material.A solgel method utilizing heterogeneous nucleation mechanism of phosphor in the aluminum sol was adopted to coat an alumina layer on the surface of strontium magnesium silicate long persistence phosphors.The crystal phases,surface morphologies,luminescent properties and thermal stability of coated phosphors were investigated and the influences of different coating amount on afterglow property and heat treatment temperature on phosphor were analyzed.The results show that it is successful to coat a welldistributed and compact aluminum layer on the surface and the coat process does not change the crystal structure of phosphor;the initial afterglow brightness of samples has a decrease tendency with the increase of coating amount;afterglow brightness appears a minimum drop and luminous intensity decreases about 10% when the coating amount is 8%;the afterglow brightness turns gradually attenuate as the rise of the heat treatment temperature;the decay brightness of uncoated sample is 0.24 and the coated is about 0.1 at 900 ℃.So surface coating improves the luminescence properties of strontium magnesium silicate phosphor
