摘要（英）：

The invention relates to 'an oxynitride luminescent material and a preparation method and application thereof', belonging to the semiconductor field. The chemical structural formula of the oxynitride luminescent material is AxByOzN2/3x+4/3y-2/3z: R, wherein, A is one of or some of materials as follows: Be, Mg, Ca, Sr, Ba, Zn. The B is one of or some of Si, Ge, Zr, Ti, B, Al, Ga, In, Li, Na and Si is included at least. The chemical characteristic of the luminescent material is stable. The luminescence performance is good. The luminescent material can get cyan or red emitting materials for white LED while being stimulated by ultraviolet or blue LDD. Of the luminescent, the wavelength stimulated is between 300-500 nm, the lighting wavelength is between 470-300nm, the lighting material is matched with blue LED or ultraviolet or near ultraviolet and can make white LED for lightening or showing light resources.
