Luminescence Characteristics of Ba_0.5Sr_0.5TiO₃:Pr_x, Al_y Powders Synthesized by Citrate-Nitride Combustion Process

Abstract:

Ba0.5Sr0.5TiO3:Pr powders co-doped with and without Al were synthesized by citrate-nitride combustion process. To investigate the effect and mechanism of Al dopant, samples with various Al3+ and Pr3+ content were prepared. The excitation and emission spectra were detected. Enhanced red emission around 613 nm was obtained by Al addition. Moreover, an emission at 491 nm was observed. Substitute situation of Pr3+ ions in the lattice was discussed. And the mechanism of energy transition was explained by the model of an intermediate charge transfer state.
