Transmission on TlIn(Se1-xSx)(2) mixed crystals (0.25 <= x <= 1) were carried out in the 400-800 nm wavelength range at T = 10 K. Band gap energies of the studied crystals were obtained using the derivative spectra of transmittance. The compositional dependence of direct band gap energy at T = 10 K revealed that as sulfur composition is increased in the mixed crystals, the direct band gap energy rises from 2.26 eV (x = 0.25) to 2.56 eV (x = 1).
