Resumo

This study deals with the development of MgB4O7:Ce,Li crystals produced by the sol‑gel synthesis as an emitter for the optically stimulated luminescence technique and the verification of structural and luminescent properties of the crystals to be inserted in a polymeric film for dosimetry applications. Further, polymeric films of PMMA (poly(methyl methacrylate)) loaded with nanocrystals of MgB4O7:Ce,Li will be synthesized to evaluate the material response to optically stimulated luminescence. We expect this hybrid material to allow neutron dosimetry for applications in Radiotherapy successfully.
