Habeeb • Films (pvp-sic) were prepared on glass slides ,by adding carborundum nanoparticles (Sic) different ratios (2, 4 and 6) wt.% to the (PVP) polymer. Optical properties studied for(PVP-Sic) films, the results of experiments showed that the optical parameters (absorbance, absorption coefficient, reflectivity, refractive index, extinction coefficient and real – imaginary dielectric constant) , it generally increases with increasing weight ratio (Nano -Sic), sublimates in the ( UV – region ) and decreases in the (Vis. and Infr. Region ). The energy band gap decreases from (3.7 ev-2.8 ev) with increase weight additive of nanoparticles, which improves electron transmission, consequently improvement optical properties of the films, therefore it can be used in optical applications (LED lights, optical devices and display screens).
