CdO/CdOZn nanoparticles were synthesised by Solution Combustion method. The synthesized particles were characterized by x-ray diffraction, ultraviolet-visible spectroscopy, field emission scanning electron microscopy, photoluminescence spectroscopy and inductively coupled plasma measurements. X-ray diffraction studies indicate that the obtained CdO/CdOZn have a cubic structure at nanoscale. The band gaps were calculated from the absorption peak of ultraviolet-visible spectrum and it was found to vary from 2.47 - 2.28 eV on Zn doping. Increase in transmittance upon Zn doping was observed. Field emission scanning electron microscopy images showed that the synthesized samples composed of nanoparticles with the average diameter of 20.8 – 34.7 nm.
