Abstract: | Highly crystalline and monodisperse In2O3 nanoparticles were successfully prepared by thermal decomposition of In(dipy)3Cl3·2H2O in oleylamine and oleic acid under inert atmosphere. The size of In2O3 nanoparticles could be readily tuned from 10–15 nm to 40–50 nm, depending on the molar ratio of precursor to combined solvent in the reaction system. As‐synthesized In2O3 nanoparticles have a center‐body cubic structure as characterized by powder X‐ray diffraction and selected‐area electron diffraction. Transmission electron microscopy images showed that In2O3 nanoparticles have a narrow size distribution. A relatively strongly PL peak centered at 378 nm could be clearly seen when 10–15 nm In2O3 nanoparticles redispersed in cyclohexane were excited at 275 nm at room temperature.
