MONOCRYSTALLINE FLUORESCENT MATERIAL FOR WHITE LIGHT-EMITTING DIODES Russian patent published in 2014 - IPC C09K11/08 C09K11/64 C09K11/77

Abstract RU 2533709 C2

FIELD: physics, optics.

SUBSTANCE: invention relates to fluorescent materials and specifically to a monocrystalline fluorescent material for white light-emitting diodes. The material is a solid solution of aluminium oxide and yttrium aluminium garnet with cerium and has a composition corresponding to the formula Y_3-xCe_xAl_5+yO_12+1.5y,where x=0.02-0.05, y=0.17-3.97.

EFFECT: high photoluminescence intensity of the fluorescent material coupled with high operational stability in varying climatic conditions.
