Sažetak
Temperature behaviour of optical absorption edge in Cu_6PS_5I_1-xBr_x mixed crystals is studied in the interval 77-325 K. It is shown that the absorption edge has Urbach shape in the 215-325 K temperature interval. The influence of temperature and compositional disorder on the Urbach absorption edge parameters is presented. The mechanism of the Urbach bundle formation and the effect of I->Br anionic substitution on the exciton-phonon interaction parameters is elucidated.
