Nonlinear optical characterization of CdTe nano particles using moiré deflectometry method

Abstract

In this paper we have been synthesized CdTe nano particles and determined the size of them by XRD pattern and TEM micrograph about 35nm. The UV-Vis spectrum of these nano particles showed an exitonic absorption peak at 600nm. Then With a CW He-Ne laser (632.8 nm: near to wavelength of exitonic peak), we measured the refractive index of these nano particles for two different incident laser powers by using moiré deflectometry method. © 2011 Published by Elsevier B.V.
