FE²�?ZNS CRYSTAL NO FURTHER A MYSTERY

Nonetheless, this peak at ~978 nm was observed in each iron-doped and -undoped ZnSe one crystals, and its integrated intensity was better in the iron-undoped sample in comparison with the iron-doped sample. As a result, we believe that the luminescence peak at ~978 nm will not be linked to the emission band involving the doped iron atoms but may po
