An object of the present invention is to provide a phosphor having a long absorption wavelength for exciting the phosphor and having a large light absorption coefficient without using ultraviolet light emission. In a phosphor based on an oxide such as gallium, aluminum or indium, the phosphor contains a rare earth element oxide such as Eu 2+ as a light emitting agent, and at least a part of the oxide is partially sulfided. A phosphor characterized by comprising: [Selection figure] None |
