高氯酸铽、六氟磷酸铽与二苯基亚砜、苯丁基亚砜配合物的发光

Luminescence of Terbium Perchlorate,Terbium Hexafluorophosphate with Diphenyl Sulfoxide and Phenyl-Butyl Sulfoxide Coordination Compounds

合成了Ｔｂ（ＤＰＳＯ）６·（ＣｌＯ４）３、Ｔｂ（ＤＰＳＯ）７·（ＰＦ６）３及Ｔｂ（ＰＢＳＯ）６·（ＣｌＯ４）３配合物（ＤＰＳＯ为二苯基亚砜ＰＢＳＯ为苯丁基亚砜）．在室温下测定了它们的固体粉末荧光激发和发射光谱，结果表明Ｔｂ（ＤＰＳＯ）６·（ＣｌＯ４）３配合物中Ｔｂ３＋的发光强度最高，其中５Ｄ４→７Ｆ５跃迁谱带强度高达８０６．２ｃｄ，Ｔｂ（ＤＰＳＯ）７（ＰＦ６）３配合物中Ｔｂ３＋发光强度次之，Ｔｂ（ＰＢＳＯ）６（ＣｌＯ４）３配合物中Ｔｂ３＋的发光强度最弱．这说明二苯亚砜做为配体受激后向Ｔｂ３＋离子传递能量的效率高于苯丁基亚砜，另外ＣｌＯ４－做为阴离子也可增加Ｔｂ３＋的发光强度，原因是部分外界ＣｌＯ４－离子可进入内界参予配位，降低了配合物的对称性，部分解除了跃迁禁律，提高了Ｔｂ３＋的发光强度．

Terbium perchlorate with diphenyl sulfoxide(DPSO) and phenyl-butyl sulfoxide(PBSO) coordination compounds bud Terbium hexafluorophosphate with diphenyl sulfoxide coordination compound have been synthesized. The resultes of composition analysis confirmed to the formula:Tb (DPSO)6. (CIO4)3, [Tb (DPSO)7] (PF6)3, Tb (PBSO)6·(CIO4)3. In the fluorescent experiments it was found that fluorescence emission intensity for Tb3+ ion in terbium perchlorate with diphenyl sulfoxide coordination compounds is highest. Because the excitation energy of DPSO ligand is very easily transferred to Tb3+ ion in Tb(DPSO)6·(CIO4)3 coordination compound.
