Influence of Microwave Power on Structural and Optical Properties of CuSe Nanoparticles Synthesized via Microwave Assisted Technique

Abstract

In the present paper, different particle size and phase of CuSe nanoparticles with hexagonal (Klockmannite) and cubic (Berzelianite) structure were successfully synthesized via microwave assisted method from CuCl2.2H2O, Na2SeO3 and hydrazine hydride (N2H4.H2O) as copper, selenium and reducing agent respectively. The influence of microwave power on structural and optical properties of CuSe NPs were investigated. The resulting nanoparticles in different sizes were characterized by X-ray diffraction (XRD). The crystallite size was calculated based on the full width at half maximum of the most intense peak in the XRD spectra using the prominent Scherer’s equation. The crystallite size was found to increase between 43.30nm to 118.70nm with the increase in microwave power. The optical properties of the as- synthesized CuSe nanoparticles were determined with the help of Photoluminescence spectroscopy (PL). The optical band gap obtained from the PL result was found to be equal to 2.03eV. Therefore, this research provides a facile synthesis method that is environmentally friendly, low cost and time saving approach to synthesized semiconductor nanomaterials that could be used for optoelectronics and solar cell applications.
