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 .
DPSO and Dyx Ho1-x (DPSO) 7 (ClO4) 3 complexes were synthesized with different concentrations of DPSO and holmium () diphenyl sulfoxide. The composition, IR spectrum and fluorescence excitation and emission spectra of the crystal were determined.The results of fluorescence spectroscopy showed that the complex has the sensitizing effect on the luminescence of Dy3 +, when doped with Ho3 + of 2/1 000 The luminescence of Dy3 + is sensitized, and the concentration range and sensitization mechanism of the sensitization of Dy3 + by Ho3 + are discussed.
