Abstract

Cadmium sulfide (CdS) nanoparticles (NPs) were synthesized using a biodegradable starch [(C₆H₁₀O₅)_n] polymer as a capping and stabilizing agent. The as-synthesized CdS NPs were highly crystalline and had a hexagonal structure with an average particle size of ~ 10.5 nm. Fourier transform infrared (FTIR) spectroscopy analysis was used to examine the presence and interactions of starch on the surface of the nanoparticles. The electronic behavior of CdS NPs was analyzed using I–V measurements and impedance spectroscopy. These NPs exhibit semiconducting behavior with resistance and conductance values of 1.78 ×10⁸ Ω, and 5.61 × 10⁻⁹ S, respectively. Photoresponse studies of CdS NPs showed significant photoresponse with improved photocurrent under light conditions. The dielectric measurements were done at different temperatures, during both the heating and cooling cycles, and the frequency dependence and temperature dependence of dielectric constant and dielectric loss were investigated.
