Fluoride phosphor, fabricating method thereof, and light-emitting apparatus and backlight module employing the same

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). A second solution is formed by mixing a surfactant and a silane (b). The first solution and the second solution are mixed to form a precipitate (c). The precipitate is collected after the first solution and the second solution are mixed (d). The steps (a, b, and c) are carried out at the room temperature. The present invention also provides a fluoride phosphor fabricated by the above method, and a light-emitting apparatus and backlight module employing the same.
