摘要：

The optical absorption spectra of CuGa0.5In0.5Se2 thin films reveal absorption humps which were attributed to valence subband transitions. (alpha-h-nu)2 vs. photon energy curves indicated a direct fundamental gap of 1.29 eV. Band splitting by crystal-field and spin-orbit effects were observed respectively at 1.39 and 1.58 eV. The crystal-field and spin-orbit parameters were estimated.
