Effect of WC nanoparticles addition on optical properties of CMC for photo-detectors devices

Abstract

In this paper, nanostructures from carboxymethyl cellulose (CMC) /tungsten carbide nanoparticles (WC NPs) were fabricated. The WC NPs was added to polymer by various weight ratios are (1.5, 3 and 4.5) wt. %. "The optical characteristics" of CMC/WC nanostructures were tested. The optical results exhibited the absorbance of CMC is raised with rising of the content of WCNPs. The gap of energy of CMC polymer reduces with a rise of the content of WCNPs. The optical constants such as "coefficient of absorption, coefficient of extinction, index of refractive", dielectric "constants for real and imaginary part"and conductivity of CMC varied with a rise of the weight ratios of WC NPs.
