Luminescent Yttrium-Aluminum Garnet Ceramics Obtained by Conventional Sintering on Air

摘要

An yttrium aluminum garnet (YAG) luminescent ceramic activated by Ce~(3+) has been obtained by uniaxial static pressing followed by sintering in air at a temperature of 1650°C. The initial phosphor powder was characterized and the linear shrinkage dynamics studied. The morphological, elastoplastic, and opticalluminescent properties of the obtained YAG:Ce ceramic samples were studied. The technological mode for manufacturing ceramics of this type with a density of at least 98% and luminescence efficiency of 45% was determined.
