Donor-acceptor transition in CuGaSe2

Abstract
In a previous paper the authors (see J. Physique, vol.41, p.707, 1980) showed by kinetics measurements a donor-acceptor transition peaked at 1.59 eV in CuGaSe2. They confirm here the fundamental parameters of this emission by measurements in terms of temperature and excitation rate. They show the influence of weak phonon coupling on intra-pairs recombination. An original deconvolution method which takes account of this influence permits the authors to find the experimental spectra again.
