Abstract

Enhancement of the ¹D₂³H₄ red emission in CaTiO₃:Pr³ with addition of nanosized SiO ₂ fabricated by a solid state reaction method is reported. The dynamical processes for the improvement of red emission were systematically investigated using photoluminescence (PL) and PL excitation spectra, and diffused reflectance spectra as well as time decay patterns of PL and persistent afterglow. Higher efficiency of energy transfer from CaTiO₃ host to the activator Pr³ due to the improvement of crystallinity by SiO ₂ addition was discussed in comparison with that of the SiO ₂ free sample. The enhancement of persistent afterglow after the cessation of excitation in SiO₂ added CaTiO₃:Pr ³ was also analyzed by theoretically fitted results.
