We use acetate and citrate combustion to prepare SrHfO3 powders both undoped and doped with Ce3+ and Pb2+ ions. The evolution of their morphological and structural features during the sintering process is studied by scanning electron microscopy, X-ray diffraction, and Raman experiments. We discuss the dependence of the optical properties, investigated by radioluminescence and time resolved luminescence, on sintering conditions and material structure.
