The nonradiative changeover rates Keep to the formulation WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the energy gap. The nonradiative transition fees of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest fees https://er-yb-yab-crystal51482.bligblogging.com/33726654/er-yb-yab-crystal-can-be-fun-for-anyone
