Article Title
Fine tuning of the sizes and phases of ZrO2 nanocrystals
Keywords
Nanocrystals, polymorphism, phase stability
Abstract
Monodisperse and pure phase zirconia (tetragonal: T-ZrO2; monoclinic: M-ZrO2) nanocrystals with fi nely tuned sizes as well as ultrathin T-ZrO2 nanowires have been selectively synthesized by a facile solvothermal method. For the fi rst time, a diagram of the size to effective strain was mapped for both T-ZrO2 and M-ZrO2, which gives a good explanation for the size- and cation doping-dependent stability of the two phases on the sub-10 nm scale. This work may expand our understanding of the phase properties of not only zirconia, but also various other polymorphic nanocrystals.
