Abstract

Multi-channel adjustable chiral liquid crystal materials with outstanding circularly polarized luminescence (CPL) have attracted lots of interest. Here, we demonstrate a coumarin 6 (C6) doped chiral liquid crystal, exhibiting crosstalk-free tunable CPL behavior by adjusting the component ratio and thickness. In the thickness study, when a double-layer structure was implemented, excellent CPL performance with a large dissymmetry factor (1.53) was observed in an optimal ratio. In particular, a rare chiroptical device using the obtained CPL as the input signal source was built to encrypt the signal transmission.
