5 SIMPLE TECHNIQUES FOR FE²�?ZNS CRYSTAL

Having said that, this peak at ~978 nm was noticed in both of those iron-doped and -undoped ZnSe solitary crystals, and its built-in depth was increased while in the iron-undoped sample in comparison While using the iron-doped sample. Hence, we feel that the luminescence peak at ~978 nm just isn't connected to the emission band involving the doped

The nonradiative transition prices Stick to the system WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy gap. The nonradiative changeover prices of Er3+ show temperature dependence in step with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest premiums is complex through the exis
