制备高质量的荧光粉,首先要制得高纯度的原材料。制备高纯原材料,不仅要提纯基质材料,也要纯制助熔剂。碱金属化合物可用作发光材料的基质,也可用作助熔剂。因此有必要研究碱金属化合物的提纯,以除去其中对发光有害的杂质。使用络合吸附色层法来提纯发光材料是一种简单易行、生产效率较高的方法。 Preparation of high-quality phosphor, we must first obtain high purity raw materials. Preparation of high purity raw materials, not only to purify the matrix material, but also pure flux. Alkali metal compounds can be used as a matrix for luminescent materials, and also as fluxing agents. Therefore, it is necessary to study the purification of alkali metal compounds to remove impurities in which light is harmful. The use of complex adsorption chromatography to purify luminescent materials is a simple and efficient method of production.
