| titleOfInvention | Vacuum ultraviolet excited aluminate phosphor and vacuum ultraviolet excited light emitting device using the same |
| abstract | An object of the present invention is to improve the baking luminance maintenance rate and the VUV luminance maintenance rate of a vacuum ultraviolet ray excited aluminate phosphor activated with europium or co-activated with europium and manganese. In a vacuum ultraviolet-excited aluminate phosphor whose general formula is expressed by the following formula, the baking luminance maintenance ratio and VUV luminance maintenance are maintained by making the M concentration on the phosphor surface smaller than the M concentration inside the phosphor. A vacuum ultraviolet ray excited aluminate phosphor having an improved rate can be obtained, and the VUV luminance maintenance rate is further improved by containing at least one element selected from the group consisting of Zn, In and Sn. A vacuum ultraviolet-excited aluminate phosphor can be obtained.
