Abstract

ZnS QDs (Quantum Dots) were dispersed in FLC mixture (SCE4). The dispersion of QDs in FLC causes enhanced Photoluminescence that can be attributed to the high molecular orderning of the composite system induced by QDs. FWHM (full width half maxima) values of peaks reveals that the presence of QDs in FLC material faours the NB (near band) emissions. The POM (Polarizing Optical Microscope) images confirms the change in the alignment of FLC molecules after the dispersion of QDs.
