The temperature dependence of the optical band gap of Tl 2 InGaS 4 single crystal in the temperature region of 300-500 K and the room temperature refractive index, n(k), have been investigated. The absorption coefficient, which was calculated from the transmittance and reflectance spectra in the inc
