Abstract
The spectroscopic properties of the six-fold (octahedral) coordinated Eu2+ in SrAl2B2O7 have been investigated. Relevant optical parameters such as the Stokes shift, crystal-field splitting, the centroid shift and the red-shift of the Eu2+ 4f65d1 electronic configuration have been estimated from the experimental data. Further, the Huang–Rhys factor and the effective phonon energy, which are responsible for electron–vibrational interactions are theoretically estimated for the Eu2+ ion in SrAl2B2O7. The low quenching temperature of the luminescence is connected with the thermally induced photoionization of the Eu2+ 4f65d1 electron. A cross-cutting comparative study of the optical properties of octahedrally coordinated Eu2+ in SrAl2B2O7 and in Cs2M2+P2O7 (M2+=Ca2+, Sr2+) is also presented.
