摘要
在乙醇和水的混合溶剂中,合成了铕(Ⅲ) 均苯三甲酸(H3L)发光配合物。通过元素分析、化学分析、热分析和红外光谱确定其化学组成为[EuL(H2O)5]·H2O。X射线衍射分析结果表明配合物为晶体物质,由扫描电镜照片可以看出配合物为棒状物质,晶粒大小10～20μm,荧光光谱分析结果表明配合物在紫外光激发下发出红色的荧光。
The luminescent chelate of Eu(Ⅲ)-trimesic acid was synthesized in the alcohol and water mixed solvent. The element analysis, the titration analysis, thermal analysis, FTIR results showed that the chelate was [EuL(H_2O)_5]·H_2O. and at the same time, XRD pattern indicated that the chelate was crystal, and SEM photograph showed that the chelate was in bar shape and the grain size was 10～20μm. PL spectra showed that the chelate emitted red luminescence under ultraviolet light.
