Preparation and characterization of Ag2E (E = Se, Te) using the sonochemically assisted polyol method

Nanocrystals of Ag2E (E = Se, Te) were prepared using the polyol reduction method under sonochemical irradiation. Particles were characterized using TEM, HRTEM, SEM, and XRD. The optical properties of the products were studied using photoacoustic spectroscopy (PAS). The differences between the as-prepared samples and single crystals and method of the nanoparticle formation are discussed.
