RESUMO

Some properties of the materials, such as ferroelectric and optic, are dependents to structural organization of the material. Thus, to know the orderdisorder degree at short, intermediate and long range is important to elucidate or predict properties in materials. The PL emission at room temperature will be used to study the structural orderdisorder at short, intermediate and long range in the CaTiO3:Sm, in function of annealed temperature. Using studies of the structural orderdisorder in the CaTiO3:Sm system will propose a model that appoint to favorable conditions, in disordered material, to show PL emission at room temperature.
