Without the assistance of any template and surfactant, In2S3 microspheres constructed with nanoflakes or nanoparticles were controllably synthesized via the hydrothermal reaction of InCl3·4H2O and Na2S2O3·5H2O in 6.25 vol.% acetic acid aqueous solution (pH = 3) at 150–180 °C for 6–24 h. The nanostructured In2S3 can be completely transformed into In2O3 when subjected to calcination in air at 600–700 °C for 5 h. The In2O3 produced at 600 °C consisted of microspheres built up with the nanoparticles of 20–30 nm in diameter. X-ray diffraction, X-ray photoelectron spectroscopy, energy dispersive X-ray spectroscopy, field emission scanning electronic microscope, Raman and photoluminescence spectra have been used to characterize the structures, compositions and optical properties of the obtained products.
