For high-power white-light-emitting diodes (LEDs) to become a technological reality there is a need to find more efficient red-emitting phosphor materials. Eu2+-doped Sr[LiAl3N4], a member of the nitridoaluminates compound class, is now proved to be a high-performance narrow-band red-emitting phosphor material that can be easily coupled with existing GaN-based blue-LED technology for use in white LEDs.
