Current effect on the structural and optical properties of the CdS nanoparticles prepared by the exploding wire technique

Abstract

This paper aims to study the effect of the explosion current on the structural and optical properties of nanoparticles prepared from cadmium sulfide as a thin film by drip casting method and then annealing of the films at 473 K. X-ray diffraction revealed that the thin films have a crystalline structure. The SEM showed that when the current increased while stabilizing the wire cross section, the particles got smaller. The optical constsnts demonstrate that the relationship is positive between the light energy gap and the average size of the nanoparticles. The remaining optical properties of the thin films were also calculated, the extinction factor and the dielectric constant were calculated in its real and imaginary parts. So we say that the current has an effect on the optical and dielectric properties of the cadmium sulfide.
