Many materials have a well-characterized refractive index, but these indexes often depend strongly upon the frequency of light, causing optical dispersion.Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength () of 589 nanometers. In this study, monometallic copper oxide nanoparticles (CuONPs) were synthesized by chemical reduction of copper sulfate (CuSO₄) salt through sugar glucose. The reduced magnitudes of transmissivity increase after reoxidation and re-exposure might be due to a initial surface conditioning and alteration on first H 2 S interaction, due to a large molar mismatch of copper oxide and copper sulfide films, as it is proposed in related works on alterations of the electrical properties (Sauerwald et al. Copper (II) oxide or cupric oxide is an inorganic compound with the formula CuO. refractive index of colors. Crown glass is a glass with a high content of potassium oxide ("potash").
