We have investigated the physical and optical properties of the left-handed chiral dopant ZLI-811 mixed in a nematic liquid crystal (LC) host BL006. The solubility of ZLI-811 in BL006 at room temperature is ~24 wt%, but can be enhanced by increasing the temperature. Consequently, the photonic band gap of the cholesteric liquid crystal (CLC) mixed with more than 24 wt% chiral dopant ZLI-811 is blue shifted as the temperature increases. Based on this property, we demonstrate two applications in thermally tunable band-pass filters and dye-doped CLC lasers.
我们研究了左旋手性掺杂剂ZLI-811与向列型液晶（LC）主体BL006混合后的物理和光学性质。室温下ZLI-811在BL006中的溶解度约为24 wt%，但可通过升高温度来提高。因此，当温度升高时，与超过24 wt%手性掺杂剂ZLI-811混合的胆甾相液晶（CLC）的光子带隙会发生蓝移。基于这一特性，我们展示了其在热可调带通滤波器和染料掺杂CLC激光器中的两种应用。
