荧光粉能够把电讯号转变为光讯号,是显示器件的关键材料之一。它自从本世纪初期发展成为工业产品以来,在工艺和生产装备上均有长足的进步,质量获得了显著的提高,新品种也不断涌现。但是,荧光粉的合成方法,绝大多数仍然沿用古典的固相反应,即由一种或几种固态粉末作为基质,再添加少量特定的阳离子和阴离子化合物作为激活剂和助熔剂,混匀后经高温煅烧而成。由这种粗放的方法制出 Phosphors can convert electrical signals into optical signals and are one of the key materials for display devices. Since its development into an industrial product in the early part of this century, it has made great strides in technology and production equipment, with significant improvements in quality and new varieties emerging. However, the phosphor synthesis method, the vast majority still follow the classical solid-phase reaction, that is, one or more solid powder as a matrix, and then add a small amount of specific cationic and anionic compounds as an activator and flux, after mixing Calcined by high temperature.
