摘要： 发现了Sm(TTA)3phen的摩擦发光现象(TL), 并对其TL光谱进行了表征. 实验结果显示, TL仍属于Sm3+离子的特征发射. 研究了稀土配合物摩擦发光现象与配体性质之间的关系, 发现配体分子的结构和性质对稀土配合物的TL性质有重要的影响: 具有强电子给体-受体(D-A)体系的配体分子有利于形成摩擦发光配合物, 且配体分子应具有一定的刚性, 从而有利于配合物形成良好的晶体.

关键词: 摩擦发光, 电子给体-受体体系, 稀土配合物

Abstract: The triboluminescence(TL) of Sm(TTA)3phen was firstly investigated, and its TL spectrum showed the characteristic transitions of the Sm3+ ion. The relationship between the TL phenomena of the rare earth complexes and the properties of the ligands was also discussed. It is suggested that the ligands with a strong electron donor-acceptor system would benefit the TL of the rare earth complexes, and the ligand molecules should be rigid enough for the growth of the rare earth complex crystals.

Key words: Triboluminescence, Electron donor-acceptor system, Rare earth complex
