This research was mainly driven by potential applicability as a photovoltaic or doping material. The refractive index determines how much the path of light is bent, or refracted, when entering a material.This is described by Snell's law of refraction, n 1 sin 1 = n 2 sin 2, where 1 and 2 are the angle of incidence and angle of refraction, respectively, of a ray crossing the interface between two media with refractive indices n 1 and n 2.The refractive indices also determine . 2013). Copper oxide has two common forms; cupric oxide (CuO), with a band gap in the range 1.2-2.1 eV and cuprous oxide (Cu 2 O), with a band gap in the range 2.1-2.6 eV [3].

Due to this low refractive index and low dispersion, crown glass is used to produce achromatic lenses. High purity copper oxide (CuO) nanoparticles (NPs) of monoclinic phase and average crystallite size of 35 nm were prepared by a simple sol-gel technique. Thus, this increment is attributed to the densification of the film. On the other hand, copper-aluminum oxide samples were deposited at 350 C but with different copper-aluminum ratios in the start solution (0, 12.5, 25, 50, 100, and 200 at%). Nonlinear refractive index increased from 2.15710 11 to 5.49510 11 in which the reason was explained by means of increment in band gap energy.
