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．
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.
