Preparation of the Cd1-xZnxSealloys in the nanophase form using microwave irradiation

Nanoparticles of the Cd1-xZnxSe alloy with different stoichiometries (x = 0.1, 0.2, 0.3) have been prepared using the microwave-assisted polyol method. In this simple and quick reaction the polyol (ethylene glycol) is both the solvent and the reducing agent. XRD studies show that nanoparticles are formed in the wurtzite (hexagonal) form with an average diameter of the nanocrystals of 5-8 nm. Electron microscopy studies show that these particles form monodisperse spherical aggregates with a diameter of approximately 200 nm. Electronic properties of the as-prepared alloys have been studied using photoacoustic spectroscopy (PAS). Also, the particles have been characterized using TGA, DSC, XPS and EDS analysis. The results of these studies are presented in this paper.
