A REVIEW OF FE²�?ZNS CRYSTAL

Nevertheless, this peak at ~978 nm was noticed in both equally iron-doped and -undoped ZnSe single crystals, and its integrated depth was bigger inside the iron-undoped sample when compared with the iron-doped sample. As a result, we feel that the luminescence peak at ~978 nm isn't connected to the emission band involving the doped iron atoms but m
