5 SIMPLE STATEMENTS ABOUT FE²�?ZNS CRYSTAL EXPLAINED

Even so, this peak at ~978 nm was noticed in the two iron-doped and -undoped ZnSe single crystals, and its built-in intensity was greater during the iron-undoped sample compared with the iron-doped sample. Therefore, we believe that the luminescence peak at ~978 nm is not associated with the emission band involving the doped iron atoms but may poss
