  • Pure complex fluorides of KMnF3 crystal of spherical plate with a diameter of about 300 nm were successfully prepared by a simple aqueous synthesis method at room temperature. The sample was characterized by X-ray diffractometer (XRD), transmission electron microscopy, and selected area electron diffraction. An XRD result proves that the product is KMnF3 of perovskite-structure. By TEM and SAED results, it is found that the spherical plate morphology of sample is formed by selforganization of KMnF3 grains. The sample shows two strong emissions at 416 and 438 nm, some discussion is made about the photoluminescence spectra and the resource of the emissions, at the same time, with the formula: Eem=-16963+164R and the photoluminescence spectrum, the bond distance of Mn-F could be estimated. Based on the obtained data it is easy to know the crystal parameter of samples with the perovskite-structure by results of photoluminescence spectra.
