Annealing effects on the luminescence properties of Ce doped ZnAl2O4 produced by combustion synthesis

ZnAl2O4 doped with varying concentrations of cerium phosphors were synthesized by combustion synthesis route. Two types of powder samples were examined: as-prepared and annealed at 800 °C in air atmosphere. We investigated the structural, morphological and photoluminescence properties of cerium doped ZnAl2O4 phosphors. Results of scanning electron microscopy, X-ray diffraction, photoluminescence investigations were presented.
