摘要
合成了高氯酸镝二苯亚砜 ( DPSO)和不同物质量比的高氯酸镝 ( )、钬 ( )二苯亚砜搀杂配合物 Dyx Ho1-x( DPSO) 7( Cl O4 ) 3.测定了配合物的组成、IR谱、粉晶荧光激发和发射光谱 .荧光光谱测定结果表明 :配合物中 Ho3+ 对 Dy3+ 发光有敏化作用 ,当掺入 2 /1 0 0 0的 Ho3+ 时即对 Dy3+ 的发光产生敏化 ,并研究讨论了 Ho3+ 对 Dy3+ 敏化的浓度范围及敏化机理 .
Dy(DPSO) 7(ClO 4) 3 and Dy x Ho 1-x (DPSO) 7(ClO 4) 3 (DPSO as the abbreviation to diphenyl sulfoxide ) have been synthesized.The Coordination compounds have been studied by means of composition analysis,infrared spectra and fluorescent excitation and emission spectra. In the fluorescent spectra it was found that Ho 3+ ion has a sensitization effect to the fluorescence of Dy 3+ ion. The fluorescent emission intensity of Dysprosium perchlorate with diphenyl sulfoxide coordination compounds would be enhanced by Ho 3+ in mixing.Ho 3+ has a sensitization to the fluorescence of Dy 3+ in the ratio of Ho 3+ /Dy x Ho 1-x = 2/1000～100/1000. ( x = 0.998～0.900).
