This paper focuses on a new but much simple approach in synthesizing cubic spinel-structure ZnGa2O4 nanowires through the reaction of β-Ga2O3 nanowires templates and ZnO vapor at high temperature. Characterization has been achieved by means of X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The length of as-synthesized ZnGa2O4 nanowires is scaled over 10 μm and the diameter is 80 nm respectively. It has been noticed that the concentration of ZnO vapor plays an important role for synthesizing ZnGa2O4 nanowires. And with different concentration of ZnO vapor, the very nanowires could be compounded in the form of β-Ga2O3:ZnGa2O4, ZnGa2O4 and ZnO:ZnGa2O4. The corresponding photoluminescence emission bands centered at 460 nm, 405 nm and 381 nm have also been observed.
