Abstract: The present invention provides a method for fabricating a fluoride phosphor. A first solution is formed by dissolving potassium fluoride (KF) and either K2MnF6 or KMnO4 in a hydrofluoric acid solution. A second solution is formed by mixing a surfactant and a silane. The first solution and the second solution are mixed to form a precipitate. The precipitate is collected after the first solution and the second solution are mixed. The present invention also provides a fluoride phosphor represented by the following formula: K2[SiF6]:Mn4+. The fluoride phosphor has a particle size in a range of about 1 μm to about 10 μm. The present invention further provides a light-emitting apparatus and backlight module employing the same.
