Abstract
We have achieved simultaneous production of gallium oxide (Ga2O3) and tin oxide (SnO2) one-dimensional (1D) nanostructures by heating a mixture of GaN and Sn powders at 900 degrees C. X-ray diffraction and transmission electron microscopy analysis revealed that the product corresponded to a mixture of monoclinic Ga2O3 nanofibers and tetragonal rutile SnO2 nanofibers. We suggest the growth mechanisms of Ga2O3 nanofibers and SnO2 nanofibers to be vapor-solid and vapor-liquid-solid processes, respectively. The photoluminescence (PL) measurement with a Gaussian fitting exhibited visible light emission bands in the blue, yellow-green, and orange regions. The PL spectrum of the mixture of Ga2O3 and SnO2 nanofibers was a combination of the PL spectra from the Ga2O3 and SnO2 nanostructures.
