摘　　要：合成了六种不同掺杂比例的稀土高氯酸盐(铽掺铥)与甲基苯甲酰甲基亚砜的固态配合物,经元素分析、稀土络合滴定确定其组成为:(T bxTmy)(C lO4)3.L5.C2H5OH(x∶y=1.000∶0.000,0.999∶0.001,0.995∶0.005,0.990∶0.010,0.950∶0.050,0.900∶0.100)。荧光光谱测定结果表明,将铥掺入铽后,可大大提高配合物中铽离子的荧光发射强度,当x∶y=0.995∶0.005时敏化强度最大,可使配合物的荧光强度增加到147%。并且在本文所研究的掺杂比例范围内,配合物中Tm3+对T b3+的发光一直起敏化作用。Five solid complexes of proportional mixed complexes （Tb^3＋ mixed by Tm^3＋） of rare earth perchlorate with the methyl-phenacyl sulfoxide have been synthesized. By elemental analysis, coordination titration. The composions of the complexes were suggested as （TbxTmy）（CLO4）3 L5C2H5OH（x ： y= 0. 999 = 0. 001, 0. 995 ： 0. 005, 0. 990 = 0. 010, 0. 950 = 0. 050, 0. 900 = 0. 100） respectively. In the fluorescent spectra it was found that the fluorescence emission intensity of Tb^3＋would be enhanced by Tm^3＋ in the mixed complexes （Tm^3＋ was mixed）. Tm^3＋ has a good sensitization to the complexes of Tb^3＋ in the ratio of 0. 995 = 0. 005. The fluorescence intensity can increase 147%. And in the ratio of Tm^3＋/Tb^2＋ = 1/1000-100/1000,Tm^3＋ has a sensitization effect all along to the fluorescence of Tb^3＋ion .
