The photoluminescence (PL) spectra of the ordered vacancy compound CuIn 5 Te 8 was measured as a function of temperature and excitation power intensity. The PL spectra show a band centered around 1.03 eV at excitation intensity of 0.3 W that shifts to higher energies with increasing excitation intensity and with decreasing temperature. The variation of the PL intensity of this band with excitation power is sublinear. Both these facts indicate that this is due to a donor-acceptor pair recombination. From the shift of this band to higher energies with P and the thermal quenching of the PL band, donor and acceptor levels with activation energy of 0.02 and 0.08 eV, respectively, were estimated.
