摘要
本文测定了两种长余辉荧光粉的吸收光谱和发射光谱，比较了其发光性能，并将其中性能较好的一种荧光粉加入常用的不饱和聚酯树脂和环氧树脂中，制得了可见光可激发的具有光致发光性能的长余辉荧光涂料。研究了其光强衰减行为。讨论了荧光粉含量、涂层厚度与荧光光强、余辉时间等的关系。
Two different long-life afterglow fluorescent powders were compared by their absorption spectrums and emission spectrums. One with better luminescent properties was used in the common unsaturated polyester and epoxy resins to form a long-life afterglow fluorescent coatings,which can be excited with visible light ,resulting in a photo luminescence. The decay of light strength and relations between fluorescent powder concentration and film thickness, and light strength and light afterglow time were discussed.
