| 摘 要： | 合成了高氯酸钐二苯亚砜Ｓｍ（ＤＰＳＯ）７·（ＣｌＯ４）３、六氟磷酸钐二苯亚砜Ｓｍ（ＤＰＳＯ）７（ＰＦ６）３、高氯酸钐苯丁基亚砜Ｓｍ（ＰＢＳＯ）７·（ＣｌＯ４）３三个配合物．测定了配合物的组成、摩尔电导及粉晶荧光激发和发射光谱．荧光光谱测定结果表明：Ｓｍ（ＤＰＳＯ）７（ＣｌＯ４）３的发光强度最高，其中４Ｇ５／２→６Ｈ７／２谱带强度高达１１９．３ｃｄ．这说明ＤＰＳＯ二苯亚砜作为配体受激发后将能量传递给Ｓｍ３＋使其敏化发光的能力高于苯了基亚砜．另外在一定的条件下阴离子ＣｌＯ可以增强Ｓｍ３＋的发光性能．

| Abstract: | Samarium perchlorate with diphenyl sulfoxide (DPSO) and phenyl-butyl sulfoxide (PBSO)coordination compounds and samarium hexafluorophosphate with diphenyl sulfoxide coordination compound have been synthesized. The results of composition analysis confirmed to the formula:Sin (DPSO)7 (CIO4 )3, Sm (DPSO )7 (PF6 )3, Sm (PBSO )7 (CIO4 )3. In the fluorscent experiments it was found that fluorescence emission intensity of Sin3 ion in samarium perchlorate with diphenyl suifoxide coordination compound is the highest and 4 G5/2-6H7/2 fluorescence emission intensity is 119. 3 cd. because the excitation energy of DPSO ligand is very easily transferred to Sm3 ion in Sm (DPSO)7 (CIO4)3 coordination compound. In addition,CIO can be enhanced fluorescence emission of Sm3 to a certain degree. |
