ABOUT FE²�?ZNS CRYSTAL

On the other hand, this peak at ~978 nm was observed in both iron-doped and -undoped ZnSe one crystals, and its built-in intensity was increased in the iron-undoped sample in comparison With all the iron-doped sample. Consequently, we feel that the luminescence peak at ~978 nm is not really related to the emission band involving the doped iron atom
