A phosphor for light sources, the emission from which lies in the short-wave optical spectral region, as a garnet structure A<SUB>3</SUB>B<SUB>5</SUB>O<SUB>12</SUB>. It is activated with Ce, the second component B representing at least one of the elements Al and Ga, and the first component A is terbium or terbium together with at least one of the elements Y, Gd, La and/or Lu. In a preferred embodiment, a phosphor having a garnet of structure (Tb<SUB>1-x-y</SUB>RE<SUB>x</SUB>Ce<SUB>y</SUB>)<SUB>3</SUB>(Al,Ga)<SUB>5</SUB>O<SUB>12</SUB>, where <?in-line-formulae description="In-line Formulae" end="lead"?>RE=Y, Gd, La and/or Lu; <?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>0<=x<=0.5-y; <?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>0<y< 0.1 <?in-line-formulae description="In-line Formulae" end="tail"?> is used.
