Resumo
The optical properties of the photoluminescence of cerium oxide doped with magnesium in the form of powders were investigated. The influence of the precursor salts of the ions of interest on the morphology and optical properties and the optical properties with excitation at different wavelengths in the visible and ultraviolet region were evaluated. The powders were synthesized by the polymeric precursor method. The structural characterization of the materials was carried out by X-ray diffraction. The symmetry of the structure was studied by Raman spectrometry. The optical transmission curves were evaluated by electron spectroscopy in the UV-Vis region. The optical properties were evaluated by photoluminescence spectroscopy and the microstructure by scanning electron microscopy.
