摘要：
We have presented absorption spectra related to octahedrally coordinated Co2+ in the Sr2+ position in SrLaGa3O7. Quantitative analysis of the line shape of the T-4(1) --> T-4(2) transition shows the existence of the strong T x tau Jahn-Teller effect in the T-4(1) 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.
