The Raman spectra of TlInS2xSe2(1-x) layered mixed crystals were studied for a wide composition range (0.25 <= x <= 1) in the frequency region 10-360 cm(-1) at room temperature. The shift of Raman-active phonon frequencies versus mixed crystals composition x were established. The effect of crystal disorder on the line width broadening of three high-frequency Raman-active modes is reported. (C) 2011 Elsevier B.V. All rights reserved.
