测定并研究了单硫代二苯甲酰甲烷（ＨＴＤＢＭ）及其稀土配合物Ｌｎ（ＴＤＢＭ）４［（Ｃ２Ｈ５）２ＮＨ］Ｈ（Ｌｎ＝除Ｃｅ、Ｔｍ外的Ｌａ－Ｌｕ）的光电子能谱（ＸＰＳ）。结果表明：Ｌｎ３＋离子通过Ｏ原子和Ｓ原子配位形成螫合物，Ｌｎ—Ｏ键和Ｌｎ—Ｓ键均具有一定程度的共价性；从Ｌａ到Ｌｕ，配位键的离子性逐渐增强；观察到Ｌａ３＋配合物３ｄ５／２具有伴峰现象。
The photoluminescence spectra of monothiobenzoylmethane (HTDBM) and its rare earth complexes Ln (TDBM) 4 [(C2H5) 2NH] H (Ln = La-Lu except Ce and Tm) XPS). The results show that Ln3 + ions coordinate with S atoms to form complexes, and the Ln-O bonds and Ln-S bonds have a certain degree of covalence. From La to Lu, the ionicity of coordination bonds gradually increases. It is observed that La3 + complex 3d5 / 2 has a peak phenomenon.
