Popis:	The steady-state photoluminescence (PL) spectra of AgInSe 2 grown by the Hot-Press method have been examined. The broad peaks located at 1.19 eV and 1.16 eV are very likely to be the donor–acceptor-pair emissions. The energies of the donor levels participating in these emissions correspondingly are 25 eV and 50–52 meV, as found from the analyses of the activation energies of the PL intensity. The peaks observed in the obtained PL spectra in the band-edge region are attributed to free and bound excitons. The binding energy of the free exciton is estimated to be 29 meV.
