Description
Summary:The optical properties of green synthesized CuO nanoparticles such as absorption coefficient, refractive index, band gap, dielectric constant and optical conductivity were analyzed. XRD shows that upon temperature treatment of green CuO nanoparticles, the crystal size increases and thus the crystallinity increases due to the decrease in the number of crystals per unit area. Due to the high crystallinity, the absorption coefficient exhibits a high electronic shift and the refractive index exhibits good polarization of the ions. Thus the dielectric constant of the real and imaginary regions decreases as the photon energy increases. Higher temperatures exhibit higher photon energy levels. Optical conductivity has induced electron annihilation due to the absorption coefficient of increased photo energy light; Hence the optical conductivity analysis of Lantana camara capped CuO nanoparticles indicated the stability of electrical conductivity with increase in photo power.
