Laser-driven solid state lighting, using laser diodes instead of light-emitting diodes as a primary source, are attracting attentions for super-brightness, compact and directional lighting. Under high power density excitation, phosphors are usually experienced luminance saturation, which making them hard to produce lighting devices with high lumen and luminous efficiency. To search for laser-driven phosphors is then a tough mission for this emerging lighting technology. In this report, we will present interesting nitride phosphors for laser-driven solid state lighting, and discuss their optical properties under blue laser irradiation.
