a XRD patterns of the products from the pure ZnO reaction, the 2% In–ZnO reaction, the 5% In–ZnO reaction, and the pure In₂O₃ reaction. The black lines are the patterns of bulk h-ZnO and c-In₂O₃ with major reflections assigned. b UV–Vis spectra of the nanocrystals from the pure ZnO reactions, the 2% In-doped ZnO reactions, the 5% In-doped ZnO reactions, and the pure In₂O₃ reactions
