Analysis of electron-vibrational interaction in interconfigurational 5d➔4f transition of Eu 2 + ions in Na 5 Ca 4 (PO 4 ) 4 F

In this paper, the photoluminescence properties of Eu -activated greenish-blue-emitting halophosphate phosphor Na Ca (PO ) 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) posi...

Description
Summary:In this paper, the photoluminescence properties of Eu -activated greenish-blue-emitting halophosphate phosphor Na Ca (PO ) 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.
