LED phosphor

       White LED has significant advantages such as high luminous efficiency, long life, energy conservation and environmental protection etc, which has a broad application prospect in the green lighting, information display, and other fields. Nitrogen/nitrogen oxide phosphors with unique excitation spectrum (excited range of ultraviolet, near ultraviolet, blue light, and even green light) as well as excellent luminescent properties (emitting green, yellow, red, small heat quenching, high luminous efficiency), non-toxic and good stability, is now the most valuable kond of new type of white LED backlight display field and LED lighting field.
      Tomley produces nitrogen/nitrogen oxide phosphors with own high purity silicon nitride and aluminum nitride as raw materials, pushing high quality and cost-effective nitrides red phosphors into the markets.
