Abstract
Metal sulfide nanomaterials have emerged an important material in recent times due to its potential applications in optical devices, nanoelectronics and nano-optoelectronics. In current research work, zinc sulfide (ZnS) nanoparticles were synthesis by simple chemical co-precipitation method and effect of calcination temperature on the structural and morphological properties of the nanomaterials have been investigated. It was observed that when temperature rises to 500 °C, cubic structure of ZnS transformed into hexagonal phase. Further increase in temperature oxidize the sulfide and ZnS changes into zinc oxide at 750 °C. This temperature rise was also evident in the SEM images where nanoparticles transformed into rod like morphology at 750 °C. Oxidation of the ZnS to ZnO also confirmed by FTIR spectrum which shows Zn-O bonds presence. These studies show that temperature variation can affect the structure and ultimately their relevant technological applications.
