Disclosed are violet, blue, and green phosphors having excellent durability and high luminance. Specifically disclosed is a phosphor which contains a metal element M (M is at least one element selected from among Mn, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Tm and Yb) for constituting a metal ion, which is solid-solubilized in an AlON crystal, an AlON solid solution crystal or an inorganic crystal having the same crystal structure as AlON. The phosphor is capable of emitting fluorescence having a peak in the wavelength range from 300 nm to 700 nm. Also disclosed is a method for producing such a phosphor. Further disclosed are an illuminating device and an image display each containing such a phosphor. |
