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.
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), ultraviolet and visible spectrum (UV-VIS), fluorescence (FS), transmission electron microscopy (TEM).
