dc.description.abstractIn this paper, electron paramagnetic resonance, photoluminescence (PL) emission, and quantum mechanical calculations were used to observe and understand the structural order-disorder of CaTiO3, paying special attention to the role of oxygen vacancy. The PL phenomenon at room temperature of CaTiO3 is directly influenced by the presence of oxygen vacancies that yield structural order-disorder. These oxygen vacancies bonded at Ti and/or Ca induce new electronic states inside the band gap. Ordered and disordered CaTiO3 was obtained by the polymeric precursor method.
