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

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).
