Copper Indium Oxide (CuInO2) nanocrystalline powder samples with different Cu/In ratios were prepared using the conventional solid-state reaction method. The structural, morphological, and optical properties of CuInO2 samples were studied. The delafossite structure of copper indium oxide nanocrystalline samples with (012) preferential orientation is observed. With altering the composition, the particles size of the prepared powder samples changed ranging from 6nm to 94 nm, and the energy band gaps varied from 2.20 eV to 2.37 eV. Photoluminescence intensity at 595 nm and 596 nm in thevisible region enhanced with variation of Cu/In ratios. |
