Structural and optical investigations on ZnCdO nanopowder

Abstract

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.

“…86-2476) and the (111) plane of CdO (JCPDS card No. 05-0640), indicating that the solubility limit is exceeded inside the host matrix (Cd 0.025 Mg 0.10 Zn 0.875 O) at 3.5% of Eu 3+ ions [18,19]; see figure 1(b).…”

Plasma-Solution Synthesis of Zinc Oxide Doped With Cadmium

“…In the works known to us, the preparation of Cd-Zn-O by the sol-gel method [4], from solutions under high pressure [5], by the pyrolysis method [6], by chemical precipitation of hydroxides from solution [7], by filtered cathode arc deposition [8] has been investigated. A relatively new method for producing oxide materials is a method based on the action of a gas discharge on aqueous solutions of metal salts.…”

Effect of the calcination process on CdO–ZnO nanocomposites by a honey-assisted combustion method for antimicrobial performance

“…The ZnO and CdO nanoparticles are similarities in the radii of zinc, cadmium and similar by other groups of elements. 22 ZnO and CdO nanocomposites have also been shown to be valuable in biological and photocatalytic applications. This type of synthesis method offers various advantages over more previously described techniques.…”
