纳米PIC-I/azaPIC-I混合分子聚集体光学非线性的Z-扫描研究

STUDY ON OPTICAL NONLINEARTIES OF NANOSTRUCTURE PIC I/azaPIC I MIXED MOLECULAR AGGREGATES BY Z SCAN

引入胶体ＳＰ５４，在室温下形成了ＰＩＣ－Ｉ（１，１，ｄｉｅｔｈｙ１－２，２，－ｃｙａｎｎｉｎｅＰ－ｔｏｌｕｅｎｅｓｕｌ－ｆｏｎａｔｅ－Ｉｏｄｉｄｅ）／ａｚａＰＩＣ－Ｉ的Ｊ－聚集体．用Ｚ－扫描技术系统研究了室温下纳米ＰＩＣ－Ｉ／ａｚａＰＩＣ－Ｉ有机分子聚集体三种配比下的三阶光学非线性．观测到随着链长变短，样品的三阶非线性极化率增大．我们分析和讨论了这种非线性增强的机制．

Adding SP54, J aggregates of PIC I/azaPIC I were formatted at room temperature. The third order nonlinearities of the aggregates at three fractions of azaPIC I were systematically studied using Z scan. It was observed that with shortening the chain lengths, χ (3) of the samples enhanced. The enhancing mechanism was discussed.
