Abstract
Carboxy-methyl cellulose (CMC)/ polyvinylpyrrolidone (PVP)/(1 − x)NiO-xZnS (x = 0, 0.25, 0.5, 0.75, 1) polymer blends were prepared using casting, sol-gel and solid state reaction methods. X-ray diffraction technique was used to determine the structure and crystallite size of the nanofillers. The crystalline feature of the blends and the nanofillers over the blends matrix were examined using the XRD technique. FTIR was used to confirm the formation of the blends. The effect of the interchangeable proportions of nanoparticles on the optoelectronic properties of the blends was examined using Wemple and DiDomenico model. The transmitted intensity is investigated with lasers at three different wavelengths. A reduction in transmittance makes the studied material promising as attenuating filters at doping levels starting from 75% NiO or less and 25% of ZnS and more even if at relatively high laser powers.
