摘要
Monodisperse and pure phase zirconia(tetragonal:T-ZrO_(2);monoclinic:M-ZrO_(2))nanocrystals with finely tuned sizes as well as ultrathin T-ZrO_(2)nanowires have been selectively synthesized by a facile solvothermal method.For the first time,a diagram of the size to effective strain was mapped for both T-ZrO_(2)and M-ZrO_(2),which gives a good explanation for the size-and cation doping-dependent stability of the two phases on the sub-10nm scale.This work may expand our understanding of the phase properties of not only zirconia,but also various other polymorphic nanocrystals.
