Impact of Quantum Dots on Refractive Index of Nematic Liquid Crystal Polymer System

Abstract

In the present study the effect of two quantum dots ZnS and CdSe on the Refractive Index of Nematic Liquid Crystal Polymer System (NLCPS) is investigated and compared. The measurement was performed for both the systems separately, using an Abbe Refractometer, within a temperature range of 20°C to 80°C with wavelengths in the visible spectrum. The refractive index with respect to temperature for various wavelengths was studied. We observed that the response of ZnS quantum dots dispersed in NLCPS was found to be better as compared to the CdSe system. This study may be useful for display and sensor applications.
