dc.description.abstract | Using Spark Plasma Sintering it is possible to produce polycrystalline ceramics of very fine microstructure and good mechanical properties. This work presents the fabrication of such ceramics using Eu3+-doped (Y0.7Gd0.3)(2)O-3 nanopowder as a starting material. We monitored the changes in the morphology of ceramic samples and their consolidation with additional thermal treatments at 650 degrees C and 1100 degrees C. The ceramics grain size remained in the sub-micron domain, even when elevated temperatures were used for annealing. The best results were obtained for the sample sintered at 1100 degrees C for 20 min, which had the smallest grain size, theoretical density, and the most intensive photoluminescence, along with the maximum hardness and appropriate fracture toughness. The Judd-Ofelt intensity parameters and branching ratios were calculated, taking into account the difference in the effective refractive index for the nanopowder and ceramic samples.
