The low-temperature transmission and wavelength modulated transmission spectra of TlGaSe2 crystals with a thickness of 7, 5.7, 4.7 μm were measured. Refractive index was calculated from interference observed in transmission spectra. The spectral dependences of the normal dispersion na (E║a) and nв (E║в) and Δn = na (E║a) − nв (E║в) on the long-wavelength and short-wave side of the ground states A, B and C of excitons are determined. |
