SYNTHESIS AND CHARACTERIZATION OF CADMIUM SELENIDE (CdSe) AND ZINC SELENIDE (ZnSe) NANOPARTICLES BY SOLID STATE REACTION METHOD

Abstract

Nanotechnology has dynamically grown as an important field of recent research with wide spread applications in the fields of electronics and medicine. Nanotechnology can be defined as an investigation for the design, synthesis, and handling of the structure of particles with a dimension smaller than 100 nm. In the present work, the author’s report the structural, optical and FT-IR properties of the Cu doped ZnS nanoparticles were synthesized by chemical method. The crystal structure studies show that samples have cubic phase crystal structure. The optical energy bandgap of pure and Cu doped samples were determined by optical study. The presence of functional groups of pure and Cu doped ZnS have been identified by FTIR study
