Abstract :

Controlling the crystal structure of inorganic solid-state compound is essential for manipulating their functional properties. Transparent metal oxides are polymorphic materials that have a range of attractive physical properties, including structural versatility, transparency, n-type conductivity, and photocatalytic activity. The phase change of metal oxides is usually achieved at high temperature or pressure. In this talk, I will review our recent kinetic studies of in situ phase transformation of In2O3 nanocrystals from metastable rhombohedral phase to stable cubic phase during their colloidal synthesis. These studies have revealed distinct mechanisms of phase transformation in reduced dimensions (surface and interface nucleation mechanisms), and the role of various parameters in this process. The influence of dopant ions on the stabilization of metastable phases and phase transformation of colloidal nanocrystals will also be discussed. I will conclude this talk by discussing the consequences of the nanocrystal phase on different functional properties, including transparency, plasmonics and light emission.
