Lighting world will change drastically due to the replacement of the traditional TL, PL and incandescent lamps by white LEDs. Advantageous features of white LEDs are a longer lifetime, lower energy consumption and extended possibilities for integration and miniaturisation. A white LED can be realized by combing a UV-blue LED with conversion phosphers, which partially convert the UV-blue light into yellow, green or red light, resulting in white light. An overview is presented of recent developments in the field of a novel class of conversion phosphors, viz. rare-earth doped silicon nitride materials, which have been investigated during the PhD research of Dr. Y.Q. Li.
