RESUMO

The aim of this work was the production and investigation of a Fe3+- doped sample. The experimental methods were X-ray diffraction, photoluminescence and photoacoustic spectroscopies. From X-ray results, the formed phases in the sample were identified. By using optical data, the excited and fundamental energy levels, the energy crystal field and Racah parameters, the radiative and non-radiative lifetimes and the Fe3+ site symmetry were determinated.
