摘要
在玻璃衬底上制得单层硬脂酸的Langmuir-Blodgett(LB)膜,做为4-戊基-4'-氰基联苯(5CB)液晶的取向层,在取向层上旋涂一层5CB液晶,用透射二次谐波方法测量出5CB液晶分子二阶非线性光学极化率,其值为β=7×10-29esu.对比文献值,测量得到的结果符合较好.
The Langmuir-Blodgett film of fatty-acid is getten on the glass substrate. The Langmuir-Blodgett film is used as the orientation layer of 4-Pentyl-4'-Cyanodiphenyl (SCB) liquid crystal. The SCB liquid crystal is coated on the orientation layer under the condition of the rotation.The molecular hyperpolarizability (β) of 5CB liquid crystal is gotten with SHG method, β value of the measurement is in accordance with the document.
