Nevertheless, this peak at ~978 nm was observed in each iron-doped and -undoped ZnSe single crystals, and its built-in depth was increased within the iron-undoped sample when compared with the iron-doped sample. Therefore, we think that the luminescence peak at ~978 nm is just not linked to the emission band involving the doped iron atoms but could
