卟啉分子L-B膜的非线性光学效应的研究

Investigation of Nonlinear Optics in Porphyrin Langmuir-Blodgett Monolayers

本文介绍了卟啉分子L-B膜在激光场作用下产生的非线性光学二次谐波效应以及利用这一效应探测卟啉分子取向特征的结果。这一实验结果为光学二次谐渡作为表面探测新手段提供了又一依据。

The second harmonic generation from the porphyrin molecules, applying a laser field, is observed. The second harmonic generation has been used to deduce the average orientation of porphyrin Langmuir-Blodgett monolayers, It is also shown that the optical second harmonic generation is one of the good probes in surface molecules research.
