2.9 Phosphors for white light-emitting diodes Recently light-emitting diodes (LEDs), particularly white LEDs, have attracted much attention as new and economically advantageous all solid-state light sources. The development of LEDs has also stimulated research on phosphors used for white LEDs; this area is presently the most active in the field of phosphors. This section describes the state-ofthe-art phosphors for white LEDs, which currently constitutes an area of high interest.
