摘要：A blue phosphor, which has excellent durability and high brightness, and inparticular a blue phosphor in a powder state, which can realize high-brightnessluminescence upon exposure to an electron beam, are provided. The phosphor beingcharacterized by comprising at least europium incorporated as a solid solution into an
inorganic crystal having a crystal structure of an AlN crystal or an AlN solid solutioncrystal, wherein the phosphor emits divalent europium-derived fluorescence having apeak at a wavelength in the range of 430 nm to 500 nm upon exposure to an excitationsource, is provided. In this case, it is more preferable that a predetermined metalelement and silicon are incorporated therein. And a manufacturing method to
manufacture such phosphor is also provided. Further, a lighting device comprising suchblue phosphor is provided.
