含三价铕荧光络合物与聚甲基丙烯酸甲酯的发光材料

PHOTOLUMINESCENCE MATERIALS CONTAINING EUROPIUM FLUORESCNECE COMPLEX AND POLY(METHYL METHACRYLATE)

用荧光性能优异的Eu(TTA) 3 ·2TPPO络合物与聚甲基丙烯酸甲酯 (PMMA)制备了一系列发出红色荧光的光致发光材料 .荧光测定结果表明 :PMMA膜的荧光强度随膜中络合物含量的增加而增大 .红外光谱研究表明络合物与PMMA之间存在相互作用 .透射电镜观测结果表明络合物在复合膜中是以亚微米颗粒分散的 .

A series of photoluminescence materials containing europium fluorescence complex and PMMA that show high intensity of fluorescence were prepared.The fluorescence spectra demonstrated that the fluorescence intensity increased with the increasing of the content of europium complex in the film.The FT\|IR study showed that there are weak interaction between the complex and PMMA.The TEM results indicated that the complex crystallize in the PMMA film and the size of the particles is 100nm to 200nm.
