| Abstract: | Photoluminescence of ZnSe doped with Na and Al has been studied. A broad band in the blue region of the spectrum has been observed at temperatures below 150 °K. This band is apparently due to donor-acceptor pair transitions involving Al donors and Na acceptors. Temperature dependence of the luminescence indicates that the Na-acceptor level is relatively shallow. |
