Abstract：BCNO luminescent materials are synthesized by precursor method. It is found that the main components of BCNO luminescent materials are B2O3, BN, and graphite by X- ray diffraction method. With the transmission electron microscopy analysis of BCNO luminescent materials, some nanocrystalline structures with lattice fringes of 0.34 nm are observed in BCNO luminescent materials. The optical measurements indicate that their maximum emission wavelength is adjustable from blue to green with the increase of excitation wavelength. Moreover, the maximum emission band of phosphor is also increase with C concentration, which is somewhat like luminescent properties of carbon quantum dots.
