Synthesis and Characterization of Copper Oxide-doped CdS Nanoparticles in PVA Matrix Thin Film and Their Application
J. Environ. Nanotechnol., Volume 14, No 2 (June 2025) pp. 238-243
Abstract
Cadmium sulphide (CdS) nanoparticles embedded in a polyvinyl alcohol (PVA) matrix were synthesized using a sol-gel technique. Doping was achieved by incorporating copper ions through copper acetate. Comprehensive characterization of the Cu-doped CdS-PVA nanocomposites was performed using particle size analysis (11 nm), UV-Visible spectroscopy (490 nm), Fourier-transform infrared spectroscopy for metal metal bond stretching, X-ray diffraction confirming crystalline nature, energy-dispersive X-ray spectroscopy for composition of elements, scanning electron microscopy, transmission electron microscopy and current-voltage studies.
