Abstract: The present disclosure provides a method for fabricating a phosphor. A first solution is formed by dissolving potassium hexafluorogermanate (K2GeF6) and either K2MnF6 or KMnO4 in a hydrofluoric acid solution. An anhydrous ethanol is added to the first solution to make a total concentration of fluoride ions of potassium hexafluorogermanate (K2GeF6), hydrofluoric acid, and either K2MnF6 or KMnO4 equal to or less than 48M to form a precipitate. Afterward, the precipitate is collected.

Abstract: 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.
