Optimization of Reaction Parameters during the Synthesis of Hexagonal Hexadecylamine Capped ZnS Nanoparticles

Abstract

Zinc sulphide nanoparticles capped with hexadecylamine (ZnS-HDA) have been synthesized through thermal decomposition of (Z)-2- (pyrrolidin-2-ylidene)thiourea zinc(II) complex. The effects of temperature, time and concentration of the precursor on the properties of ZnS-HDA capped nanoparticles were investigated. The values of the optical band edges were increasing when the temperature, reaction tim and the amount of the precursor were elevated. X-ray diffraction patterns of all the synthesized nanoparticles mainly exhibited hexagonal phase structures. The morphologies of the particles were increasing with the increase in temperature, time and precursor concentration.
