Preparation of Stochiometric Cu2S Nanoparticles by Ultrasonic Method

This study reports on the synthesis of Cu2S nanoparticles via an ultrasonic method by employing Na2SO3 as a reducing agent This method is novel, simple and can be easily controlled. Effects of power and time of sonication were investigated. Morphology, structure, and composition of the obtained products were characterized by X-ray diffraction (XRD), energy dispersive X-ray analysis (EDX), scanning electron microscope (SEM) and photoluminescence (PL) spectroscopy. The effects of time and power of irradiation were studied. XRD calculations show that the average crystallite diameter of Cu2S nanoparticle is about 25 nm. The calculated band gap of Cu2S nanosparticle (2.24 eV) shows obvious blue shift. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/3508
