Oxynitride LED Phosphor Powder Description
A phosphor is a substance that exhibits luminescence; it emits light when exposed to a specific type of radiation energy. Oxynitride LED phosphor powder is characterised by chemical stability, thermal stability and durability. It is non‐toxic, non‐radioactive and non‐corrosive.
Stanford Advanced Materials (SAM) has over two decades of experience in the manufacture and supply of LED phosphor in various forms and is your main point of contact for the procurement of Oxynitride LED phosphor powder meeting industry specifications.

Oxynitride LED Phosphor Powder Application
Phosphor layers provide the majority of the light generated by fluorescent lamps and are used to improve the light balance of halogen metal halide lamps. Various illuminated signage utilise phosphor layers to produce different light colours. Electroluminescence displays, such as those found in aircraft instrument panels, employ a phosphor layer to generate glare‐free illumination or serve as numerical and graphical display devices. White LED lamps consist of a blue or ultraviolet emitter with a phosphor coating that emits at longer wavelengths thereby reproducing the full spectrum of visible light.
In combination with red and green phosphor powders, Oxynitride LED phosphor powder can be utilised to generate white LED light with a CRI of Ra95 or higher. Generally, Oxynitride LED phosphor emits a blue‐hued light when used with blue chips.
