Description
Summary:ZnCdO nanocrystalline powder is synthesized by the simple solution method at room temperature. Synthesized powder was characterized by powder x-ray diffraction (XRD), scanning electron microscope with x-ray spectrometry (EDX), thermo gravimetry-differential thermal analysis (TG-DTA) and other spectroscopic techniques. The XRD pattern exhibited a mixture of hexagonal ZnO and cubic cadmium oxide phases. The crystallite size of the prepared powder was found to be around 28 nm. Surface morphology of sample was determined by scanning electron microscopy and the distribution of Zn, Cd and oxygen species in the prepared sample was identified by chemical composition mapping through EDX. TG-DTA curves indicate the thermal stability of the prepared sample. The photoluminescence spectrum shows the bands in ultra-violet and blue emission regions. The Fourier transform infrared spectrum demonstrates the presence of metal oxide vibrations.
