The cadmium (Cd) doped zinc oxide (ZnO) nanoparticles were prepared under room temperature by changing the doping concentration using simple chemical method. The obtained nanoparticles 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 3.6 eV. An enhanced emission nature was observed from the PL emission spectrum
