三价铕激活硫氧化钇荧光粉是彩色电视(CTV)屏幕中广泛使用的主要红色材料,采用硫化物熔融法制备。应用非均匀形核理论,讨论了使用多硫化钠助熔剂在氧化钇铕上生长氧硫化钇体系的形成过程中所获得的一些新结果。
Trivalent europium-activated yttrium oxysulfide phosphor material prepared by a sulfide fusion method is the primary red material used extensively in color television (CTV) screens. Applying the heterogeneous nucleation theory, we discuss some new results obtained on the formation process of the yttrium oxysulfide system grown on yttrium-europium oxide using sodium (poly) sulfide flux.
