These remarkable properties make them promising semiconducting materials in photonic applications. A series of (TlGaS2)x?(TlGaSe2)1?x layered mixed crystals grown by Bridgman method were investigated from the standpoint of their Raman spectroscopy characteristics. Experimental Raman scattering study of crystals were reported in the frequency range of 80–400 cm?1 for compositions of x = 0, 0.25, 0.50, 0.75 and 1.0. The effects of crystal disorder on the line-width broadening of Raman-active modes were studied in detail. The asymmetry in the Raman line-shape was analyzed for two highest-frequency intralayer mode presenting two-mode behavior. It was shown that mixed crystal disorder effect is the major source for change of Raman line-shape with composition. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.en10.1007/s10854-020-03990-8info:eu-repo/semantics/closedAccessCrystal growth from meltCrystalsNonlinear opticsRaman scatteringSelenium compoundsSemiconducting gallium compoundsSemiconducting selenium compoundsCompositional dependenceOptical nonlinearityPhotonic applicationRaman active modesRaman measurementsSemiconducting compoundsSemiconducting materialsTwo-mode behaviorSulfur compoundsArticle31171433014335Q3WOS:0005482608000052-s2.0-85087816836Q2
