X-ray line broadening analysis and optical studies of surfactant EDTA assisted rare earth ion cerium doped ZnS nanocrystals.

Abstract

We report a simple chemical precipitation method for the synthesis of EDTA capped cerium doped ZnS nanocrystals with an average size of around 2.88 nm. X-ray diffraction results revealed that the products were crystalline with cubic phase. Crystallite size and strain were estimated by Williamson–Hall (W–H) plots drawn using x-ray diffraction data. Compared with uncapped products, 5% of EDTA capped ZnS shows enhanced PL intensity ratio and suggesting a new class of luminescent material for the fabrication of optoelectronic devices.
