ABSTRACT
The ferroelectric liquid crystals (FLC) composites with improved electro-optic properties, obtained by incorporating CdSe (CS) nanoplatelets (NPLs), are reported. Noticeable improvementin optical contrast, saturation voltage, response time, and brightness of FLC have been found. The improvements of electro-optical properties are the results of enhanced molecular alignment of FLC due to the presence of CS NPLs. Time resolved photoluminescence (TRPL) measurements reveal NPLs surface energy transfer in FLC. Two types of Fӧrster resonant energy transfer (FRET) is observed in CS incorporated FLC. First is homo FRET which is the transfer of exciton within stacked CS NPLs and second is FRET between FLC and CS NPLs. FRET are supporting the CS incorporated FLC to get superior electro-optic properties. These findings may create opportunity of future CS NPLs incorporated FLC based display devices having better electro-optical properties.
