摘要
本文合成Ｌａ（Ⅲ）、Ｇｄ（Ⅲ）、Ｔｂ（Ⅲ）８－羟基喹啉固体配合物，通过对其光声光谱的分析。
hydroxyquinoline complexes of La(Ⅲ)、Gd(Ⅲ) and Tb(Ⅲ) were synthesized and the photoacoustic(PA)spectra of these complexes were measured in the region of 300—800nm at room temperature.The PA spectra and excitation spectra are compared and interpreted.It is observed that the photoacoustic spectra and the excitation spectra behave complementarily.The different fluorescence properties of the complexes and the relaxation process models are studied by the photoacoustic amplitude and phase spectra.It is confirmed by the PA phase spectrum that the PA absorption of π π transition of Tb( O x) 3 complex is dominantly contributed by the slow radiationless relaxation which is due to inner molecular energy transfer.
