| Popis: | The time resolved spectra and the dependence on the excitation intensity of the phonon assisted edge emission of CdSe single crystals have been measured in the temperature range 4·2–77°K. It is concluded that at 4·2°K this emission is mainly due to the electronic transitions between donor-acceptor pairs, while at higher temperatures the contribution of free to bound transitions may become dominant. Values of the ionization energies of donor and acceptor involved have been obtained. |
