Abstract
The invention relates to the field of inorganic functional materials, and discloses a Mn<4+>-doped alkali metal fluoro-phosphate red luminescent material and a preparation method thereof. The chemicalcomposition of the Mn<4+> doped alkali metal fluoro-phosphate red luminescent material is AP1-xF6:xMn<4+>, wherein x is the molar percentage coefficient of correspondingly doped Mn<4+> ions relativeto P<5+> ions, and x is greater than 0 and less than or equal to 0.10; and A is Cs, Rb or K. The provided red luminescent material is mainly used for emitting red light of about 633 nm under the excitation of blue light, and the light emitting efficiency is high. The preparation method of the Mn<4+>-doped alkali metal fluoro-phosphate red luminescent material is an ion exchange method, the synthesis process is simple, and the preparation method is suitable for large-scale industrial production.
