Abstract

The invention pertains to the field of lighting technology using InGaN-based blue LEDs and specifically to luminescent materials containing yttrium oxide  oxides of rare earth metals as well as aluminium oxide in proportions that yield a luminescent material whose average composition fits the general formula   where a - defines increase in stoichiometric index over the known value for yttrium-gadolinium garnet and varies between 0.033 and 2; x - is atomic fraction of cerium  0.0001-0.1; - is one or more lanthanides from the Gd  Tb  La  Yb group  whose atomic fraction in an yttrium sub-lattice is 0 01 <Gd< 0 70; 0 001<Tb<0 2; 0 001<La<0 1; 0 001<Yb<0 1   respectively  while the difference for all the compositions [1–x–y] > 0.
