The third order nonlinearities of the aggregates at three fractions of aza PIC-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. 纳米混合分子聚集体 三阶光学非线性 Z－扫描 nanostruture mixed molecular aggregate third order nonlinearity Z-scan 国家自然科学基金;中国科学院激发态物理开放研究实验室资助 1998-03-30 1998-11-30 2021-03-18 4 19
