Transparent zinc oxide ceramics, undoped and doped with 0.1-2.0 wt% Er 3+ ions were fabricated by uniaxial hot pressing of commercial oxide powders. The ceramics were characterized by X-ray diffraction, SEM, EDX, Raman, X-ray and optical spectroscopy. The analysis of morphology of Er 3+ :ZnO ceramics reveals that the main components of texture are hexagonal prism planes similar to those for undoped ceramic. The ZnO grain size decreases with addition of Er 2 O 3 . The Er 3+ ions are distributed between the ZnO grains and the Er 2 O 3 crystals and do not enter the zinc oxide structure. The luminescence spectra of Er 3+ :ZnO ceramics contain emission bands originating from the intra-4f shell transitions of Er 3+ ions and bands assigned to defect states at ZnO. The X-ray luminescence spectra indicate the possible energy-transfer between the ZnO grains and Er 3+ ions. The defect luminescence band becomes weaker and the X-ray luminescence decay time decreases as the erbium concentration is increased.
