Macroscopic and microscopic investigation of a blue oxynitride phosphor Universiteit Gent
Solid state lighting (SSL) has proven to be the sole viable alternative to replace energy consuming incandescent or mercury based lighting technology. Light-emitting diodes or LEDs are gaining market share every day although improvements in color rendering and luminous efficacy are still desirable. In white LEDs, the intrinsically narrow emission band of the pumping diode is combined with one or multiple phosphor materials which convert a part ...
