合成了六种高氯酸掺杂稀土(Dy3+,Tm3+)与二苯甲酰基甲基亚砜的配合物。经元素分析、稀土络合滴定、摩尔电导率及差热-热重分析，表明配合物组成为 (Dyx，Tmy)L5(ClO4)3·3H2O(x∶y=1.000∶0.000,0.995∶0.005,0.990∶0.010,0.950∶0.050,0.900∶0.100,0.800∶0.200;L=C6H5COCH2SOCH2COC6H5)。并详细讨论了六种稀土配合物的荧光光谱。从配合物的荧光光谱图可以看出，Tm3+对Dy3+的荧光有增强效应。这可能是因为在惰性稀土离子Tm3+与活性稀土离子Dy3+之间有能量的传递。而且当Dy3+与Tm3+的量比为0.950∶0.050时，掺杂配合物表现出最佳的发光性质。另外，Tm3+对577.4 nm处4F9/2→6H13/2 峰的荧光敏化作用的程度高于对487 nm处4F9/2→6H15/2 峰的荧光敏化作用。4F9/2→6H15/2 峰的荧光强度增强了212％，而4F9/2→6H13/2峰的荧光强度增强了264％。所以，Dy3+离子的两个特征峰的发射强度比趋近于1，为1.078，使得配合物在紫外灯下发白色荧光。有可能成为一类发白色荧光的发光材料。

Complexes of (Dyx,Tmy)L5(ClO4)3·3H2O(x∶y=1.000∶0.000, 0.995∶0.005,0.990∶0.010,0.950∶0.050,0.900∶0.100,0.800∶0.200;L=C6H5COCH2SOCH2COC6H5)were synthesized. The properties of the complexes were characterized with elemental analysis, infrared spectra (IR) and ultraviolet absorption spectra. The fluorescence spectra of these complexes were discussed in detail, indicating that the fluorescence intensity of Dy (Ⅲ) is enhanced by Tm (Ⅲ). This phenomenon may be due to the intra-molecular energy transfer. The complex shows the best luminescence properties when the ratio of Dy (Ⅲ) to Tm (Ⅲ) is 0.950∶0.050. As a result, the complexes can emit white fluorescence under the ultraviolet excitation. It is predicted the complexes will become a class of luminescence materials that emit white fluorescence.
