| Popis: | Photoluminescence spectra of ZnSe single crystals doped with Au during a long high-temperature treatment of as-grown crystals in Zn + Au or Se + Au melts are investigated in the temperature range from 83 to 300 K. The Au-doping from Zn + Au melt leads to the formation of both simple defects (Au i donors and Au Z n acceptors) and acceptor associates (Au Z n -Au i ). The edge luminescence is attributed to radiative annihilation of Au; and V S e donor-bound excitons. The edge spectra of the crystals doped with Au from Se + Au melt contain the band ascribed to radiative annihilation of Au Z n acceptor-bound excitons. |
