摘要：
A fluoride phosphor including a sheet-like crystal and a manufacturing method and an application therefore are disclosed. The fluoride phosphor has a chemical formula A2[MF6]:Mn4+, with Mn4+ as an activator. The A is Li, Na, K, Rb, Cs, NH4 or a combination thereof. The M is Ge, Si, Sn, Ti, Zr or a combination thereof. The sheet-like crystal has a thickness d. A crystal flat surface of the sheet-like crystal has a maximum length a. The maximum length a is defined as a distance between two end points on an edge of the crystal flat surface and farthest from each other. 8≤a/d≤35.
