In the last few years, white light-emitting diodes (white-LEDs) have been the subject of increasing interest due to their potential applications in indicators, backlights, automobile headlights, and general illumination [1]. They possess many excellent features such as long lifetime, mercury free, high energy efficiency, and compactness. In the case of the phosphor-converted LEDs either organic dyes or inorganic phosphors have been used as down-conversion materials [1, 2, 3, 4, 5]. However, the lifetime of organic materials is too short, and some environmental problems arise from the preparation and use of inorganic phosphors as they contain toxic elements, such as sulfur, chlorine, and cadmium. To solve these problems, novel phosphors without environmental hazards should be developed.

Recently, rare earth doped (oxy)nitride phosphors are gaining considerable attention due to their promising luminescent properties that enable them to use in white-LEDs, fluorescent lamps, and flat panel...
