Photoluminescence spectra of TlInSe2 crystals with quasi one-dimensional structure have been investigated. The observed broad spectra have been found to result from overlapping of two peaks centered at 1.05 and 0.97 eV. Following the results of the examination of the excitation intensity dependence of the observed photoluminescence, the last peaks have been attributed to free-to-bound radiative transitions. The activation energy of donor or acceptor levels associated with these emissions has been tentatively evaluated. Furthermore, two sharp peaks located at 1.17 and 1.23 eV have been observed at 10 K in the excitation spectra of the observed photoluminescence. © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
