Mild solvothermal synthesis of KZnF_3 and KCdF_3 nanocrystals

摘要

KZnF_3 and KCdF_3 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(CH_3CO_2)_2 centre dot 2H_2O (M=Zn, Cd) and KF centre dot 2H_2O in MeOH was investigated by variation of reaction temperature, reaction time and molar ratio of starting materials, which indicated that KZnF_3 and KCdF_3 nanocrystals could be controllably synthesized.
