Metastable γ‐Ga 2 O 3 nanoflowers assembled from hexagonal nanopetals are successfully constructed by the oxidation of metallic Ga in acetone solution. The nanoflowers with a hollow interior structure exhibit a short response time and a large light‐current–dark‐current ratio under a relatively low bias voltage, suggesting an especially important potential application in solar‐blind photodetection.
