Study of Quasi-Monodisperse In2O3 Nanocrystals: Synthesis and Optical Determination

Abstract

In this communication, we report a successful synthesis of quasi-monodisperse In₂O₃ nanocrystals with high crystallinity in a high-temperature organic solution. The average size of nanocrystals can be tuned using a dynamic injection technique. TEM and XRD investigations indicate that each nanocrystal is a single crystal. The optical determination implies that the photoluminescence behavior of these In₂O₃ nanocrystals is different from that of the bulk, probably due to the combination of weak quantum-confinement-effects and the nature of high crystallinity in nanocrystals.
