摘要： The present disclosure provides a red phosphor powder, a preparation method thereof and a luminescent device comprising the red phosphor powder. The red phosphor powder comprises inorganic compounds containing an element A, an element D, an element X and manganese, wherein element A is one or more selected from a group of Li, Na and K and necessarily includes K; element D is composed of Ge and Si, or element D is composed of Si, Ge and Ti; and element X is one or more selected from a group of F, Br and Cl and necessarily includes F; and the inorganic compound has the same space group structure as K2GeF6, the space group structure being the hexagonal crystal system P-63mc(186). The red phosphor powder has a uniform morphology, a high luminescent efficiency and a good stability.
