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.
