摘要
Photoluminescence study as a function of excitation intensity has been performed in CuInTe2 at 4.2 K. From the analysis of the data, using the current theoretical models, all the emission lines observed in the PL spectra have been identified: These are due to free-exciton (1.053 eV), bound-excitons (1.047, 1.044, 1.040 and 1.030 eV), donor-to-acceptor (1.022 and 1.017 eV) and donor-to-valence band (1.033 eV) recombination processes.
