Abstract
ABSTRACTWe report the enhancement in the molecular ordering of ferroelectric liquid crystal (FLC) doped with CdSe/ZnSe graded core/shell (CZ) quantum dots (QDs) by using optical methods. Significant decrease in operating voltage and enhancement in optical brightness are assigned to the large primary order parameter (θ) and hence anchoring of FLC molecules by CZ QDs. The enhancement in photoluminescence is conjectured to be due to an increase in molecular alignment yielding higher absorption which is confirmed by excitation spectra. These observations would definitely offer a promising tool to get superior core/shell QD incorporated FLC-based display devices.
