FE²�?ZNS CRYSTAL NO FURTHER A MYSTERY

Nevertheless, this peak at ~978 nm was observed in equally iron-doped and -undoped ZnSe solitary crystals, and its built-in intensity was larger during the iron-undoped sample in comparison with the iron-doped sample. Thus, we believe that the luminescence peak at ~978 nm will not be connected with the emission band involving the doped iron atoms b
