VACUUM ULTRAVIOLET EXCITED GREEN PHOSPHOR MATERIAL AND LIGHT-EMITTING DEVICE USING THE SAME

摘要

This invention is intended to overcome the problems with conventional phosphor materials, specifically to overcome the problems of insufficient luminance and of color impurity on the screens of color display units when green phosphor materials have blue or red light emission. This invention is intended to provide vacuum ultraviolet excited green phosphor materials that include terbium, gadolinium-doped rare-earth aluminum scandium borate represented by the following general formula: (Y1-x-yGdxTby)Al3-zScz(BO3)4 (0<=x<0.5, 0
