Electron–vibrational interaction in 5d state of Ce3+ ion in (LiMg/Li2Na/Li3)BF6 phosphors

• The EVI parameters such as Huang–Rhys factor, effective phonon energy and zero phonon line position were estimated.
• Ce3+ ion emission observed in LiMgBF6, Li2NaBF6 and Li3BF6.
• Material analyzed in this work has large FWHM, large Stokes shift and large effective phonon energy.

The electron–vibrational interaction (EVI) parameters such as Huang–Rhys factor, effective phonon energy and zero phonon line position were estimated using data from our recent reported work, on photoluminescence in rare earth doped complex hexafluorides phosphors LiMgBF6, Li2NaBF6 and Li3BF6 Validity of results were established by modeling the emission line which was found to be in good agreement with experimental photoluminescence spectra.
