We have investigated the quantitative relationship between the polytypes and the direct and indirect exciton gap energies in GaSe1−xSx mixed crystals. The X-ray diffraction analysis shows that GaSe1−xSx is the ε-type for 0(GaSe)≤x\lesssim0.01, the γ-type for 0.05\lesssimx\lesssim0.4, the β-type for 0.5\lesssimx≤1(GaS), and a mixture of the ε- and γ-types for 0.01\lesssimx\lesssim0.03. The direct and indirect exciton gap energies are determined from optical absorption and luminescence excitation spectra. The plots of the direct and indirect exciton gap energies vs the compositional parameter x show kinks in the neighborhood of x=0.4. Furthermore, a jump in the indirect exciton gap energy is found at around x=0.02. These anomalies at x=0.02 and 0.4 are attributed to the ε-γ and γ-β polytype transformations, respectively.
