Luminescence properties of YAl 3 (BO 3 ) 4 (YAB) and Y 1– x Sc x Al 3 (BO 3 ) 4 (YSAB) have been investigated under vacuum ultraviolet (VUV) light excitation. In YAB, two emission bands peaking at 3.2 and 3.9 eV are observed. On the other hand, there appear two emission bands at 3.2 eV and about 4.1 eV in YSAB. The origins of these emission bands are ascribed to two kinds of BO 3 atomic groups. We suppose that the shift of the peak around 4 eV band is deeply related to the fact that one kind of BO 3 atomic groups of YSAB are significantly distorted compared to that of YAB.
