Abstract
A convenient sonochemical process for the preparation of silver selenide (Ag 2 Se) nanoparticles by using different complexing agents [NH 3 , citric acid, potassium thiocyanate (KSCN)] and hydrazine as reductant agent is developed. It was found that pure Ag 2 Se nanoparticles were prepared in the presence of KSCN after 90 minutes of sonication. The products were characterised by X-ray diffraction, scanning electron microscopy and energy-dispersive X-ray spectroscopy analysis. Photoluminescence was used to study the optical properties of Ag 2 Se samples.
