| Abstract: | The reflection, absorption and luminescence spectra of the lowest excitons in AgGaS2 are measured in magnetic fields. The results can be explained by the quasicubic model. The exchange splittings of the Γ4, Γ5 and Γ3 exciton state are evaluated. The Zeeman splittings of the Γ5 and Γ5-Γ3 states yield g-values of + 3.8 and 3.7, respectively. They are determined mainly by the contributions of the hole and conduction electron spins. |
