含过渡金属离子的有机玻璃的合成及其荧光性能研究

Preparation and Luminescent Properties of Polymethyl Methacrylate Containing Transition Metal Ions

采用本体共聚合的方法,以甲基丙烯酸铜(钴)、甲基丙烯酸甲酯为原料,合成了含铜(钴)离子的有色有机玻璃制品,对产品的荧光性能进行了分析。结果表明,引入铜离子能大幅度增强产品的发射光强度。此法制备的产品可作为优良的光致发光材料。

By using Copper（Cobalt） methacrylate and Methyl methacrylate as starting material, Polymethyl methacrylate doped with copper（cobalt） ions were prepared through bulk polymerization method. PMMA doped with copper ions was blue and transparent, while PMMA doped with cobalt ions was green and transparent. The fluorescence properties of products were analyzed through fluorescent spectrum. It is found that fluorescent emission intensity increased greatly by doping transition metal ions and Cu2＋-doped PMMA are potential host material with long persistent fluorescence that can be activated by visible light.
