Abstract
We report the synthesis of micron-sized vesicles of carbon encapsulating In2O3 nanocrystals, as well as neat In2O 3 nanocrystals. The thermal decomposition of In(acetate)3 was carried out at 800°C in air. This reaction was carried out under the autogenic pressure of indium acetate. The synthesized products were systematically characterized by X-ray powder diffraction, scanning electron microscopy, and transmission electron microscopy. Carbon microvesicles, with an average diameter of 5 μm, encapsulated several nanometric-sized In 2O3 nanocrystals, as evidenced by high resolution transmission electron microscopy. The UV/Vis absorption of In2O 3 nanocrystals was studied to estimate the bandgap energies.
