Anisotropic Shape Control of Colloidal Inorganic Nanocrystals

The systematic shape control of colloidal nanocrystals including one-dimensional (1D) nanorods remains a key issue in the “bottom–up” approach of nanoscience. Here, we examine the anisotropic structural evolution of various semiconductor nanocrystals and systematically elucidate the key growth parameters for their shape control. The crystalline phase of nucleating seeds and kinetic growth regimes controlled by changing growth parameters are crucial for the determination of the 1D nanocrystal geometry.
