摘要
合成了铕 (Ⅲ )的二苯甲酰甲烷、三正辛胺的三元配合物Eu3 + ·(DBM ) 3 · [N(C8H17) 3 ]2 ,通过元素分析确定了配合物的组成 ,并通过红外光谱对配合物进行了表征。结合红外光谱、荧光光谱讨论了配合物的成键特性、配体传能机制以及协同配体N(C8H17) 3 引入对激发光谱的影响。荧光光谱表明配合物可吸收 2 4 7～ 4 0 0nm的宽带紫外光 ,发射Eu3 + 的5D0 →7F2 对应的 6 12nm红色荧光。
The ternary Eu 3+ complex with dibenzoyl methane (DBM )and tri n octyl amine \[N(C 8 H 17 ) 3 \] has been prepared. The composition of the complex was determined to be Eu 3+ ·(DBM) 3 ·\[N(C 8H 17 ) 3\] 2 by chemical and elemental analysis. This structure was further characterized by FT IR spectra. The bonding property and energy transfer mechanism in the Eu 3+ complex and the effect of the second ligand, N(C 8 H 17 ) 3 \], on the excitation spectra were discussed by FT IR and fluorescence spectra. Fluorescence spectrum showed that the complex could absorb wide band of ultraviolet light of 247～400nm region and emit 612nm red light related to transition of 5 D o → 7 F 2, on the excitation spectra were discussed by FT IR and fluorescence spectra. Fluorescence spectrum showed that the complex could absorb wide band of ultraviolet light of 247～400nm region and emit 612nm red light related to transition of 5 D o → 7 F 2 in Eu 3+ .The complex can be used as a light transfer agent in agricultural plastic films.
