铝酸锶铕类长余辉荧光涂料的研究

Studies on Steady Persistence Fluorescent Coating with 4(Sr, Eu)O·7Al 2O 3

测定了市售铝酸锶铕类长余辉荧光粉的吸收光谱和发射光谱，研究了其发光性能；将其加入常用的不饱和聚酯树脂ＵＰ和环氧树脂ＥＰ中，制得了用可见光可激发的具有光致发光性能的长余辉荧光涂料，研究了这些涂料的光强衰减行为，讨论了荧光粉的加入对涂层粘度、荧光光强、余辉时间、硬度、吸水率等的影响．

A new kind of fluorescent coating was prepared by adding 4(Sr, Eu)O·7Al 2O 3,which is a kind of steady persistence fluorescent powder, into unsaturated polyester (UP) resin and epoxy (EP) resin respectively. The decay behavior of steady persistence fluorescent coating was studied. Effects of the addition of fluorescent powder on luminous properties, viscosity, surface hardness, water adsorption of UP resin and EP resin were discussed.
