Abstract

Using the experimental setup for poling film samples with capability of continuous monitoring of generation signal of second harmonic, the conditions of effective orientation of chromophore molecules based on polyfluoro-substituted triaryl pyrazoline and dicyan-substituted isophoron in micron films of polycarbonate are determined. The second harmonic is excited with the pulse Nd:YAG laser with 1064 nm when chromophore molecules are oriented in the field of corona discharge. The dependences of signal level of the second harmonic on the potential at field mesh and on the potential at needle electrode are measured.

通过测量二次谐波的产生信号确定电晕放电场中发色团-聚合物膜的极化条件

摘要

使用具有连续监测二次谐波产生信号能力的极化膜样品的实验装置，确定了聚碳酸酯微米膜中基于多氟取代的三芳基吡唑啉和双氰基取代的异佛尔酮的发色团分子的有效取向条件。当发色团分子在电晕放电领域中取向时，二次谐波由具有1064 nm的Nd：YAG脉冲激光激发。测量了二次谐波的信号电平与场网处的电势以及针电极上的电势的相关性。
