摘要
报导了镧、镨、钕、钐、锖氯化物与二甲基亚砜、邻菲啰啉混配配合物的合成及其荧光性能?峁砻?氯化铕-二甲基亚砜-邻菲啰啉混配配合物在紫外光激发下,在可见光区辐射高强度荧光。
The preparation of a number of complexes of LnCl_3(where Ln=La,Pr,Nd,Sm and Eu) with dimethyl sulfoxide and 1,10-phenanthroline is reported. The composition of the complexes is characterized by elemental analysis,IR and TG-DTA. The exitation and emission, as well as the fluorescent intensity are measured on dried and finely powered sampies at room temperature. The bright brown-red fluorescent lines of complex Eu(DMSO)(Phen)_2Cl_3 at about 600 nm are assigned to the transition from ~5D_i levels to all multiple levels of ~7F_i.
