FIELD: chemistry.
SUBSTANCE: invention relates to lighting engineering and can be used in blue LEDs of solid-state white light sources. The luminescent material based on yttrium aluminate, which contains cerium oxide, has the general formula (Y1-xCex)3±αAl5O12+1.5α, where x is the atomic fraction of cerium which is equal to 0.01-0.20; 0<α≤0.5 or 0>α≥-1.5. The colour temperature of the solid-state white light source varies from 3500 K to 4500 K.
EFFECT: colour coordinates and brightness are comparable with commercial samples.
