ABOUT FE²�?ZNS CRYSTAL

Even so, this peak at ~978 nm was noticed in the two iron-doped and -undoped ZnSe single crystals, and its built-in depth was bigger while in the iron-undoped sample compared Together with the iron-doped sample. Hence, we feel that the luminescence peak at ~978 nm just isn't associated with the emission band involving the doped iron atoms but may p
