Abstract: The structures of silicon-based (oxy) nitrides are generally built up of networks constructed from linked SiX_4(X=O,N) tetrahedra. The silicon-based (oxy) nitride phosphors had been considered as promising down-conversion phosphors for white LED owing to their high thermal and chemical stability, and excellent photoluminescence properties. The chemical composition and structure, luminescence properties and improvement methods of silicon-based (oxy) nitride phosphors systems were well summarized. At last, the development and application in white LED of the silicon-based (oxy) nitride phosphors were indicated.

Key words: white light emitting diode%phosphor%(oxy) nitrides
