The cadmium sulphide (CdS) nanoparticles were prepared using simple chemical method under room temperature by changing the different mole ratio. The synthesised NPs structural, morphological, optical properties were characterized by using X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet visible spectroscopy (UV) and photoluminescence spectroscopy (PL) techniques. A cubic crystal structure was observed from the XRD analysis and their calculated crystallite sizes were approximately ±15 nm. A blue-shifted optical absorption nature was observed from UV spectrum and their calculated bandgap energy value was approximately 3.8 eV.
