The photoluminescence spectroscopy of undoped CdTe crystals provides information on two acceptors which are the main contaminants of as-grown crystals. These acceptors called y and z have their respective ionization energies a t 147 and 108 meV. A complete series o f two hole replicas iu observed for y and only one for z. These acceptors are believed to be due to Cu and A@; impurities. Backdoping experiments with Li and Na give rise to new transitions. From the conduction bandacceptor level transitions, t,he ionization energies are respectively obtained to 57.8 and 58.8 meV. In the case of Li, some extra-lines are tentatively identified as phonon interacting two-hole transitions.La spectroscopie de la photoluminescence de CdTe non dope fournit des informations sur deus nccepteurs qui sont des contaminants du matkriau brut de croissance.
