Mild solvothermal synthesis of KZnF3 and KCdF3 nanocrystals

KZnF3 and KCdF3 nanocrystals have been prepared via a mild solvothermal route, and characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). The reaction between M(CH3CO2)2·2H2O (M=Zn, Cd) and KF·2H2O in MeOH was investigated by variation of reaction temperature, reaction time and molar ratio of starting materials, which indicated that KZnF3 and KCdF3 nanocrystals could be controllably synthesized.
