荧光性Eu(Ⅲ)-DB21C7纳米配合物的溶剂热合成

Synthesis of Eu(Ⅲ) Coordination Nanocomplex with Dibenzo21crown7ether Via Solvothermal Approach

摘要:

利用微乳液体系（硝酸铕水溶液/CTAB/配体有机溶液/正己烷），通过溶剂热法，合成出了荧光性铕(Ⅲ)二苯并二十一冠七醚（DB21C7）纳米配合物［Eu(DB21C7)2(NO3)3］.并运用元素分析（EA）、傅立叶红外光谱（FTIR）、紫外可见光谱（UVVIS）、荧光光谱（FS）、透射电镜（TEM），对其组成、形貌以及光学性质进行了表征.

Abstract:

The fluorescence nanosized europium(Ⅲ) coordination nanocomplex of ［Eu(DB21C7)2(NO3)3］ with dibenzo21crown7ether have been successfully synthesized via solvothermal approach in microemulsion（EuNO3 aqueous/CTAB/ ligand organic/hexane）.The composition,morphology and the optical properties have been characterized by element analysis,Fourier transform infrared spectrum (FTIR),ultraviolet and visible spectrum(UVVIS),fluorescence(FS),transmission electron microscopy (TEM).
