Role of localized phonon vibration in luminescence performance of Pr doped Ba(Mg0.28Zr0.16Ta0.56)O3 transparent ceramics
文献摘要：
Oxygen-assisted high temperature solid-state reaction approach was employed for the fabrication of Pr activated Ba(Mgo.28Zr0.16Ta0.56)O3 transparent ceramic phosphor.Retiveld refinement of X-ray diffraction pattern was carried out to reveal the lattice parameters and crystal structural information.Under the blue-light excitation of λex=473 nm,the phosphor exhibits a sharp intense red emission centered at 645 nm,accompanied by several other weak peaks.PL evolution with temperature shows a significant luminescence quenching behavior,and the underlying multi-phonon interaction with optical center is revealed by proposing an unprecedent theoretical calculation work.Such a phonon effect is further confirmed from the red-shift of peak position with temperature,and the involved phonon energy of 50.7 meV is determined from Raman scattering measurement.More interestingly,the fitted results of transient-state PL spectra show a fluctuation of luminescence lifetime at various temperatures,further indicating a significant effect of phonon vibration in the system.
