Abstract in another language
CaAlSiN3:Eu powder compacts were pressureless-sintered in a nitrogen atmosphere between 1400 and 1800 °C. The sintering behavior and the dependence of the luminescence properties on the sintering temperature were investigated. It is shown for the first time that it is possible to sinter CaAlSiN3:Eu ceramics that efficiently emit light starting from a micrometer-sized phosphor powder optimized for high luminescence efficiency. The maximum densities of the ceramics were achieved at ≥ 1700 °C and are limited to 80 % of the solid-state density owing to inhomogeneities of the powder compacts caused by the applied binder-free dry-pressing procedure. The phase composition of the ceramic specimens as well as the luminescence properties remained unchanged during sintering. These results demonstrate that pressureless sintering is suitable for fabricating CaAlSiN3:Eu bulk ceramics that can be used for LED applications.
