When quantum dots meet blue phase liquid crystal elastomers

Circularly polarized luminescence (CPL) materials have attracted tremendous attention for their potential applications in many fields, such as molecular sensors, information encryption, and optical storage. So far, using cholesteric liquid crystals (CLCs) with helical superstructure has proved to be an effective media of amplifying glum value. However, CPL materials constructed by small molecule CLCs are often confined to LC cells, limiting their practical applications in certain scenarios.
