Ultrasound-assisted synthesis of highly disperse zinc sulphide powders

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 deg C, at different pH values, using variable reagent concentrations. All samples were characterized by infr...

Summary: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 deg 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.
