Abstract
The samples of CdS semiconductor nanoparticles with varying molar concentration were synthesized by wet chemical route at room temperature. Structural characterization of synthesized CdS semiconductor nanoparticles were performed by X-ray diffraction pattern (XRD) while optical characterization were examined by UV-Visible absorption spectroscopy. XRD pattern showed the as synthesized CdS nanoparticles have cubic (zinc blend) structure with average crystallite size 12.23–9.02 nm and lattice constant a= 5.829 Ǻ. UV-Visible absorption spectrum showed the band gap energy of the CdS nanoparticles are found in the range of 2.55-2.63 eV. The increase in band gap with the decrease of crystallite size of the nanoparticles is due to quantum confinement effect.
