5 SIMPLE STATEMENTS ABOUT FE²�?ZNS CRYSTAL EXPLAINED

Nevertheless, this peak at ~978 nm was observed in each iron-doped and -undoped ZnSe single crystals, and its integrated intensity was higher while in the iron-undoped sample in comparison with the iron-doped sample. Thus, we believe that the luminescence peak at ~978 nm will not be relevant to the emission band involving the doped iron atoms but m
