摘要
光声位相作为光声光谱重要的一部分 ,包含着很多有价值的信息 ,对它的研究可以获得其它光谱甚至光声振幅谱都不能得到的信息。光声位相在测定样品的光学和热学性质、样品无辐射弛豫过程的研究以及深度剖面分析等方面显示了特有的能力。本文结合本实验室近几年的工作 ,在光声光谱理论的基础上 ,对光声位相理论及其在化学中的应用作一综述。
Photoacoustic phase is an important part of the photoacoustic spectroscopy (PAS). It contains valuable information. A study on it may acquire information that can not be obtained from other spectroscopy even from the photoacoustic amplitude. Photoacoustic phase shows the special ability of measuring the optical and thermal properties, studying the nonradiative relaxation processes and analyzing the depth profile of the sample and so on. In this paper, combined with the recent research at our lab and based on the theories of photoacoustic spectroscopy, the application of the theories of the photoacoustic phase to the chemistry is reviewed systematically.
