Photoluminescence spectra of Tl 4 GaIn 3 S 8 layered crystals grown by Bridgman method have been studied in the wavelength region of 500-780 nm and in the temperature range of 26-130 K with extrinsic excitation source (Ξ» exc = 532 nm), and at T = 26 K with intrinsic excitation source (Ξ» exc = 406 nm
