Beschreibung
Zusammenfassung:	The present invention relates to a process for the preparation of MN doped fluoride phosphors. A method for synthesizing a color stable Mn4 + doped phosphor includes contacting a precursor of formula I, I, II, III, or IV with a fluorine-containing oxidizing agent in gaseous form at an elevated temperature to form the color stable Mn4 + doped phosphor. 本发明涉及用于制备MN掺杂的氟化物磷光体的方法。一种用于合成颜色稳定的Mn4+掺杂的磷光体的方法，包括在升高的温度下，使式I、I、II、III或IV的前体与呈气体形式的含氟氧化剂接触，以形成颜色稳定的Mn4+掺杂的磷光体。
