Abstract
Optical properties of acousto-optical material Tl3SbS3 were investigated at the fundamental absorption edge. The basic (n = 1) and excited (n = 2, 3) exciton states were obtained from the λ-modulated reflection spectra for polarizations Eâ¥c at 10 K. Taking into account the spatial dispersion we determined the parameters of excitons by calculating the spectra shapes of λ-modulated reflection of line n = 1 and estimated values of the zone-translation masse and the reduced effective masse of excitons, the effective masse of electrons (mC1â=0.12m0), heavy (mV1â=0.88m0) and light (mV2â=0.196m0) holes.
