利用双光束耦合实验研究了14种铁电液晶与一种光电导化合物混合后的光致发光性能。研究了低分子量FLC的性质对光折变效应的影响，发现FLC的性质对光折变双光束耦合增益系数和折射率光栅形成时间有很强的依赖性。在此基础上讨论了自发极化强度、粘度和表面稳定态的均匀性对FLC光致发光活性的影响。
The photorefractivity of 14 ferroelectric liquid crystals (FLCs) mixed with a photoconductive compound was investigated by two-beam coupling experiments. The influence of the properties of low-molecular-weight FLCs on the photorefractive effect was examined, and it was found that the photorefractive two-beam coupling gain coefficients and the refractive index grating formation time are strongly dependent on the properties of FLCs. The effects of the magnitude of the spontaneous polarization, the viscosity, and the homogeneity of the surface-stabilized state on the photorefractivities of FLCs are discussed based on these findings.
