The temperature dependencies of bands 2.374 eV (A), 2.570 eV (E) and 2.576 eV (F) for TlInS2 are interpreted by supposing that the crystal undergoes structural phase transitions. Band A is considered to come from a donor-acceptor recombination channel. © 1995.EnglishA. ferroelectricsA. semiconductorsD. optical propertiesD. phase transitionsE. luminescenceBand structureCrystal symmetryCrystalsFerroelectric materialsLow temperature effectsOptical propertiesPhase transitionsPhotoluminescenceThallium compoundsLow temperature photoluminescence spectraMixed crystalsThallium indium gallium sulfideSemiconducting indium compoundsArticle10.1016/0038-1098(95)00037-2
