Abstract

Highly disperse zinc sulphide powders have been synthesized using an ultrasound-assisted reaction between zinc acetate and thioacetamide in aqueous solution. The synthesis was performed at 70°C, at different pH values, using variable reagent concentrations. All samples were characterized by infrared absorption spectroscopy (FT-IR), thermal analysis (TGA-SDTA), scanning electron microscopy (SEM) and photoluminescence spectroscopy (PL). A correlation between the preparation conditions and zinc sulphide characteristics was established..
