Abstract
We have presented absorption spectra related to octahedrally coordinated Co2+ in the Sr2+ position in SrLaGa3O7. Quantitative analysis of the line shape of the 4T1→4T2 transition shows the existence of the strong T⊗τ Jahn-Teller effect in the 4T1 ground state of the system. We have estimated the Jahn-Teller stabilization energy to be equal to 507 cm-1. The procedure of estimation of the crystal-field strength parameter 10Dq for the system that is affected by the strong Jahn-Teller coupling has been discussed.Keywords
