Photoluminescence studies of chalcopyrite CuInTe 2 were conducted. Three edge (1.041 eV, 1.030 eV, and 1.019 eV) and two deep level (0.999 eV and 0.957 eV) emission bands were observed at 11 K. The excitation intensity dependence of PL spectra was recorded. As possible band sources one excitonic and four band‐to‐defect recombination mechanisms are proposed in this paper.
