X-ray diffraction and IR spectroscopy for nano-sized ITO doped with some metal oxides

摘要: Nanocrystalline indium tin oxide (ITO) doped with 2, 4 and 6 mole% of CuO, Cr2O3, and ZrO2 powder have been synthesized by pechini method. The crystalline structure of all the prepared samples was identified using XRD and IR spectroscopy. The morphology and average grain size of the prepared powder were determined using TEM and XRD. The effect of different dopant, different concentration, dopant cation valence and ionic radius on the crystalline structure, lattice parameter, crystallite size and strain were investigated. All samples have single cubic bixbyite phase structure except ITO samples doped with Zr. They have cubic bixbyite structure as predominant phase and traces of rhombohedral phase. Pure ITO sample has higher lattice parameter value than those of ITO samples doped with ZrO2 and lower lattice parameter value than those of ITO samples doped with CuO and Cr2O3.[AM Youssef, HA Abbas, FF Hammad, AMA Hassan, and ZM Hanafi.
