Effect of vacuum sintering conditions on the properties of Y3Al5O12: Ce luminescent ceramics

The aim of this work was to study the effect of vacuum sintering conditions and cerium concentration on the optical, luminescent and thermal properties of yttrium-aluminum garnet based ceramics doped with Се3+ cations. Series of ceramic powders were synthesized and samples of luminescent ceramics ha...
