摘要：

Bulk ZnTe and CdTe single crystals were grown using Cl-, Br-, and I-containing transporting gas agents. Photoluminescence spectra consisting of a free-exciton band and a low-energy band of extrinsic origin were studied at various temperatures, excitation levels, and time delays. It is shown that the low-energy band can be assigned to the emission of donor-acceptor pairs. No noticeable differences were observed between the emission spectra of crystals grown with Cl, Br, and I. (C) 2002 MAIK "Nauka/Interperiodica".
