A luminescent material, containing yttrium oxide, oxides of rare-earth metals, as well as aluminium, gallium and indium oxides in a ratio that produces compounds corresponding to the general formula : [in-line-formulae][(Y1-x-y-zCexΣ(Ln-1)yΣ(Ln-2)z]3-α(Al1-p-qGapInq)5O12-1.5α[/in-line-formulae] where α is a value varying within the 0.20≦α≦2.80 range; x is cerium atomic fraction, varying in the 0.0010; p and q are atomic fractions of Ga and In in the aluminium sub-lattice. Their ranges are : 0
