Synthesis and properties of delafossite CuAlO2 nanowires
Source abstract
Abstract
Ultra-long and uniform CuAlO2 nanowires were successfully synthesized within a porous anodic aluminum oxide template by means of sol–gel method at 900 °C. The results of X-Ray diffraction indicate that the obtained CuAlO2 nanowires have a single delafossite structure. The scanning electron microscopy and transmission electron microscopy show that the CuAlO2 nanowires have a uniform diameter with about 50 nm and a length up to 10 μm. Room-temperature photoluminescence measurement of nanowires exhibits an ultraviolet near-band-edge emission around 350 nm (3.54 eV).
