Abstract: A light emitting device includes a Light Emitting Diode (LED) having a light emitting surface, a silicon nitride layer on the light emitting surface and a sealed environment surrounding the light emitting surface. The silicon nitride layer may be directly on and cover the light emitting surface. The silicon nitride layer may completely cover the light emitting surface. The silicon nitride layer may provide a substance blocking layer such as a moisture blocking layer and/or a carbon blocking layer that can prevent moisture and/or carbon, such as Volatile Organic Compounds (VOCs) that contain carbon, from reaching the light emitting surface.

Abstract: Light emitting devices and components having excellent chemical resistance and related methods are disclosed. In one embodiment, a component of a light emitting device can include a silver (Ag) portion, which can be silver on a substrate, and a protective layer disposed over the Ag portion. The protective layer can at least partially include an inorganic material for increasing the chemical resistance of the Ag portion.
