Using copper sulphate pentahydrate and sodium hydroxide pellets Copper Oxide (CuO) nanopowder is synthesized via solid state co-precipitation technique. The as-prepared CuO nanopowder is characterized by XRD, FESEM, UV–Vis absorption and photoluminescence Spectroscopy. XRD studies reveals that CuO nanoparticles are in monoclinic structure with crystalline size is found to be around 15 nm estimated from Scherrer formula. FESEM measurement shows that particles are in almost irregular shape and some nanorod like structures are obtained. The UV – Vis absorption and photoluminescence measurements are made in different solvents. A strong quantization with varying band edge in different solvents is found from UV–Vis absorption measurements. From photoluminescence spectra it is seen that the intensity of emission as-well-as emission peak wavelength changes with solvent. [ABSTRACT FROM AUTHOR] |
