Synthesis and Characterization of CdS Nanoparticles for LED Application

Jyotsna Chauhan, Varsha R. Mehto, Dharmendra Kumar

Abstract


In the present work we have synthesized the size tuned CdS nanoparticles with chemical routes method. Size of the nanoparticle tuned with varying the addition of an appropriate quantity of capping agent. UV spectroscopy used to study the variation of optical properties with tuning the size of nanoparticle. EMA and TBM techniques are used to analyze size and band gap of the quantum dots.

Keywords
