dc.description.abstract | The present study demonstrates how petal‐shaped copper oxide (CuO) nano‐rod structures
were fabricated using the microwave‐assisted combustion method. The prepared material
was annealed at a temperature of 500°C and characterized by means of optical absorption
spectroscopy (UV–Vis), X‐ray diffraction (XRD), Field emission scanning electron
microscopy (FE‐SEM), and Photo‐conductivity technique (I‐V characteristics). The optical
energy gap of CuO nano‐rods was analysed through the UV–Vis NIR spectroscopic
technique and the result illustrates that the energy gap of synthesised CuO nano‐rods is
found to be 1.44 eV. The XRD of the synthesised sample confirms that copper oxide nanorods
are in pure monoclinic phase with lattice parameters x=4.675 Å, y=3.343 Å, z=5.183 Å.
Energy dispersive analysis using X‐rays confirms the existence of copper and oxygen atoms
in synthesised CuO nanocrystals. FE‐SEM micrographs specify that the synthesised material
contains nanostructured nano‐rods with a small amount of agglomeration in the product.
The electrical properties of CuO film were studied through I‐V characterization and the
results depict that the conductance of CuO film is found to be superior under UV‐ light
compared to in the dark. | en_US |
