Synthesis of pure and Cr doped Zinc Sulfide nanoparticles for charge transport layers applications

Abstract

Pure Zinc Sulfide (ZnS) and Chromium doped Zinc Sulfide (Cr-ZnS) nanoparticles have been prepared by chemical precipitation method. The XRD patterns of Pure ZnS and Cr doped ZnS nanoparticles exhibit zinc blende and Hexagonal wurtzite phases with the average grain size of about 10 nm. The elemental composition of pure ZnS and Cr doped ZnS was confirmed by Energy Dispersive X-ray Analysis (EDX). The optical band gap of pure ZnS and Cr doped ZnS was found to be 3.4 eV and 3.25 eV respectively. The surface morphology of the pure ZnS reveals the formation of agglomeration the nanoparticles and Cr doped ZnS nanoparticles leads to nanopetals like structures.
