绿色长余辉磷光材料的研究

用化学元素（Ｓｒ，Ｚｎ，Ｃｄ）的硫化物为基质，所制作的磷光材料是一种无毒、无放射性污染、使用安全的高新技术产品，其发光亮度能满足低度照明和指示标识之需，且耗电能小，并能长期重复使用。着重阐述该生产方法和工艺流程，列举了主要技术指标，对一些影响因素进行讨论，并介绍磷光材料的应用情况。

A Study on Phosphorescent Material with Long Green Afterglow

The phosphoreseent material with the sulphide of strontium, zinc, or cadmium as host is a newhigh-tec product. It is safe from toxicity and radioactive contamination. With a low luminous emittance, itwill serve as a low illuminant and an indication mark. With a low power consumption, it can be repeatedlyused over a long time. A presentation is made on the technology of its production, its technical norms, influencing factors and applications.
