| 摘 要： | 测定了三种用来制备Ｌａｎｇｍｕｉｒ－Ｂｌｏｄｇｅｔｔ（Ｌ－Ｂ）膜的苯乙烯吡啶盐染料分子的拉曼光谱。实验发现，在光照射下，碳碳双键的拉曼峰强度逐渐变小，由此证实了这类有机染料分子在光照射下碳碳双键发生断键，这可能是引起Ｌ－Ｂ膜光学二次谐波信号随时间减小的主要原因。

| Abstract: | The Raman spectra of organic molecules of three stilbazole salt dyes to be used for Langmuir-Blodgett (L-B) films preparation have been measured. The experiments show that under irradiation the intensity of Raman peak of C=C bonds diminished gradually. This shows that the C=C bonds in these molecules breaks under irradiation, the latter may be the main course for the optic second harmonic wave signals of L-B film diminishing. |
