摘要
提出了利用透过光谱法和吸收光谱法相结合测定聚合物电光系数的一种新方法 ,并求得了合成的聚氨酯聚合物薄膜在 632 .8nm处的电光系数为γ33=34 .4 pm/V ,γ13=5.4 pm/V。
A new method has been developed to measure electro-optic coefficients of poled polymer film based on the combination of transmission spectum and absorption spectrum.The electro-optic coefficients are determined as γ 33 =34.4 pm/V, and γ 13 =5.4 pm/V,respectively, at 632.8 nm for a new synthesized polyurethane film.
