通过电场诱导的双折射-双折射跃迁调制了双折射液晶主体中客体分子的荧光发射。两种状态之间的对比度可以大于15，并且主要受客体的相和序参数的散射性质的影响。数据上的对比度的依赖关系的细胞参数和结构的客人和主机。一个简单的模型，占所观察到的行为。
Fluorescence emission of guest molecules in cholesteric liquid crystal hosts was modulated by an electric‐field‐induced cholesteric‐nematic transition. The contrast ratio between the two states can be greater than 15, and is affected primarily by the scattering properties of the phase and the order parameter of the guest. Data are presented on the dependence of the contrast ratio on the cell parameters and the structure of both guest and host. A simple model is presented accounting for the observed behavior.
