铝酸锶蓄光型发光材料的研究

Study on the Luminescence Glost Material of Storage Light Such as Strontium Aluminate

蓄光型发光材料是近年来应用比较广泛的一种发光材料。笔者选用铝酸锶铕镝体系,以高温固相法、共沉淀法、微波法、溶胶—凝胶法等制备发光材料,并通过控制不同原料的配比、pH值、温度等条件,探讨了上述因素变化与材料发光特性之间的关系。

Luminescence glost material of storage light is used extensively in recent years. The subject selects strontium aluminate activated by europium, dysprosium system. Luminescence materials are prepared by the high temperature, the coprecipitation, the microwave, and the sol - gel method, etc., Through controlling the different matching, pH value, temperature, etc., this paper discussed the relationship between the raw materials matching, the preparing methods and luminescence characteristics.
