Abstract

In this work, avocado peel extract was used as a capping and reducing agent for preparing CdS nanoparticles. UV-Vis spectrophotometry was used to study the absorbance and to found the optimal conditions for formation CdS nanoparticles. The band gap was found to be 3.25 eV, suggesting the effect of quantum size. The XRD pattern explain that the as-formation CdS particles are crystalline with cubic phase. FESEM images explain that the nanoparticles have spherical shape with an average size of 22 nm. The optical properties of CdS NPs such as the coefficient of absorption, refraction, and diffraction were calculated using mathematical equations.
