Phase transformation of ultrathin nanowires through lanthanide doping: From InOOH to rh-In_2O_3

摘要

The effect of Gd~(3+) doping is harnessed to promote the phase transformation of ultrathin (2 nm) InOOH nanowires to corundum In _2O_3 and to stabilize the nanowires against morphological deformation. The approach described here suggests a new route toward morphology and phase control of In_2O_3 nanocrystals, which could be applied to prepare other nanocrystals.
