【 摘 要 】

A convenient sonochemical process for the preparation of silver selenide (Ag2Se) nanoparticles by using different complexing agents [NH3, citric acid, potassium thiocyanate (KSCN)] and hydrazine as reductant agent is developed. It was found that pure Ag2Se 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 Ag2Se samples.
