Experimental and Theoretical NANOTECHNOLOGY (ETN) abbreviated as Exp. Theo. NANOTECHNOLOGY is a multidisciplinary peer-reviewed and open access journal. It includes specialized research papers, short communications, reviews and selected conference papers in special issues on the characterization, synthesis, processing, structure and properties of different principles and applications of nanotechnology with focus on advantageous achievements and applications for the specialists in engineering, chemistry, physics, materials science and medicine. ETN covers and publishes all aspects of fundamental and applied researches of experimental and theoretical nanoscale technology dealing with materials synthesis, processing, nanofabrication, nanoprobes, spectroscopy, properties, biological systems, nanostructures, nanoelectronics, nano-optics, nano-mechanics, nanodevices, nanobiotechnology, nanomedicine, nanotoxicology within the scope of the journal. ETN aims to acquire the recent and outstanding researches for the benefit of the human being.
In this work a surfactant free microwave method for preparation of Cu2S nanostructure is reported. Cu2S nanostructures (without formation of other phases such as CuS and Cu1.8S) were prepared using Na2SO3 as a weak reducing agent. The effect of different parameters such as time and power of irradiation on the morphology and particle size of the samples have been investigated. The nanostructures were characterized by X-ray diffraction (XRD), energydispersive X-ray analysis (EDX), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR), photoluminescence (PL) and ultraviolet-visible (UV-vis) spectroscopy. Keywords: Nanostructure; Semiconductors; Cu2S.
