Abstract
In the present work, we have synthesized the CuO nanorods via a complex precipitation method using NH3 H2O as a complexing agent. Structural analysis by X-ray diffraction, Fourier transform infrared spectroscopy and EDXS revealed the formation of single phase CuO with a monoclinic crystal structure. Morphological analysis by Field Emission scanning electron microscopy showed the formation of CuO architecture. Optical analysis by UV–vis spectroscopy showed blue-shift in the optical band gap due to quantum confinement effect and light harvesting efficiency of CuO in Tabernaemontana Divaricata dye solution is also discussed. Photoluminescence spectroscopy has been employed in order to explore the optical emission properties of CuO nanorods. The growth mechanism for the formation of CuO nanorods has been proposed.
