Analysis of electron-vibrational interaction in interconfigurational 5d➔4f transition of Eu2+ ions in Na5 Ca4 (PO4 )4 F

In this paper, the photoluminescence properties of Eu2+ -activated greenish-blue-emitting halophosphate phosphor Na5 Ca4 (PO4 )4 F were studied to estimate electron-vibrational interaction (EVI) parameters such as the Huang-Rhys factor, effective phonon energy, Stokes shift and zero phonon line (ZPL...

Zusammenfassung:In this paper, the photoluminescence properties of Eu2+ -activated greenish-blue-emitting halophosphate phosphor Na5 Ca4 (PO4 )4 F were studied to estimate electron-vibrational interaction (EVI) parameters such as the Huang-Rhys factor, effective phonon energy, Stokes shift and zero phonon line (ZPL) position for various concentrations of dopant. The validity of the results was established by modeling the emission spectra, which was found to be in good agreement with the experimental photoluminescence spectra.
