Effect of Grain-Size and Pb Dopant on Luminescence in BaTiO3
Photoluminescence spectra of Ba1-xPbxTiO3 with grain sizes of 60 nm have been obtained. Different emission bands for pure BaTiO3 have been separately obtained against two excitation lines of 488.0 and 514.5 nm. Based on the dependence of the visible emission band upon Pb content and excitation power, a model that describes the origin of visible emission has been suggested.
