Czech J Phys 11 374376 1961. The 200 and 400 C samples have similar characteristics but clearly differ from the characteristics of the additionally prepared copper sulfide samples Full size image. Such directional scattering is experimentally observed on colloidal Cu 2 O nanospheres which are readily prepared through wet-chemistry methods.
The thickness and the refractive index of Cu2O nanostructures were determined using different methods. From the image the refractive index of CuO nanoparticles is found to increase with an increase in photon energy whereas it is found to have lesser value than that for the bulk CuO n 26. The n0 values are 9 for Cu and 25 for CuO and Cu 2 O 26.
