Abstract

This letter reports photoluminescence properties of nanocrystalline BaTiO₃. Two intense emission bands centered at 543 and 694 nm and a weak one at 574 nm have been observed at room temperature. The change of luminescence peak with different heat treatments correlates to the evolution of Ti⁴⁺ defects in the nanocrystalline BaTiO₃ matrice. The light-emission mechanism is explained within the framework of self-trapped excitons by combining quantum-size confinement and dielectric confinement effects.
