Abstract

ZnS has remarkable properties that can be utilized for versatile applications including field emitters, flat panel displays, electroluminescence, photoluminescence, catalyst and biosensors (Ummartyotin, et. al, 2016). Besides ZnS has low cost and enviromentally benign material.
Compared to bulk ZnS, nano ZnS possess distinctive physical and chemical properties such as: enhanced surface to volume ratio, the quantum size effect, macroscopic quantum tunneling effect, more optical absorption, chemical activity and thermal resistance, enhanced performance, enhanced shell-life and the low melting point (Kaur et. al, 2016). ZnS is considered more suitable for visible and UV light based devices than ZnO (3.4 eV) since ZnS exhibit large band gap of approximately 3.54 eV and 3.91 eV for its two polymorphs, zinc blend and wurtzite respectively. For the fabrication of ZnS
nanoparticles there exist various methods such as chemical precipitation, sol-gel, hydrothermal, inert-gas evaporation etc. in the literature (Wang et.al, 2013) Most of these methods needs some special equipments to apply high temperature, high pressure and inert media with difficult processing conditions.
In this study, we reported a simple and green method to synthesize ZnS nanoparticles which were characterized by XRD, XPS, FTIR, UV-Vis. and SEM.
