Abstract

The refractive indices of the cholesteric liquid crystal solution were measured using multiwavelength (visible range) refractometer for three different wavelengths. Measurements were made at different temperatures for various concentrations of the solution, mixing CLC in a soluble solvent. Vuks equation describes the wavelength and temperature dependence of refractive indices of anisotropic crystalline materials. We have used a simplified version of Vuks equation relating only to macroscopic indices and verified its validity for five-different-concentration solution at various temperatures. The result is also used to obtain molecular polarizabilities and temperature dependent material constants of our sample.

空心棱镜折射仪对Vuks方程的实验验证
采用多波长(可见光范围)折光计测量了胆甾液晶溶液在三种不同波长下的折射率。在不同温度下对不同浓度的溶液进行测量,将CLC与可溶性溶剂混合。Vuks方程描述了各向异性晶体材料折射率对波长和温度的依赖关系。我们使用了Vuks方程的简化版本,仅涉及宏观指标,并验证了其在不同温度下五种不同浓度溶液的有效性。该结果还用于获得我们样品的分子极化率和温度相关的材料常数。
