Well‐defined indium hydroxide [In(OH) 3 ] nanocubes have been successfully prepared through a facile single‐microemulsion‐mediated hydrothermal process at a relatively low temperature. Calcination of the In(OH) 3 precursor at 400°C in a furnace yielded In 2 O 3 crystals with the same morphology. X‐ray diffraction (XRD), field‐emission scanning electron microscopy (FE‐SEM), and transmission electron microscopy (TEM) were used to characterize the samples. The effects of reaction parameters on the formation of nanostructures were also discussed, and the nucleation, aggregation and anisotropic growth mechanism was proposed. Room temperature photoluminescence (PL) spectra as well as the ultraviolet‐visible (UV‐vis) absorbance spectra were carried out on the In 2 O 3 crystals to investigate their optical properties.
