摘要
The complex fluoride, KNiF3, with perovskite structure was synthesized by refluxing KF and Ni(NO3)2·6H20 in ethanediol. The samples were characterized by X-ray diffraction(XRD), transmission electron microscopy(TEM), X-ray photoelectron spectroscopy(XPS), and ultraviolet-visible diffuse reflectance speetroseopy(UV-Vis DRS). The results indicate that the mean diameter of KNiF3 particles is about 30-60 nm and the oxygen content in the samples is ≤5%. The prepared KNiF3 shows obvious absorption peaks at 400-830 nm.
