The nonradiative transition fees Keep to the formulation 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 consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace charges is https://erybyabcrystal19640.thechapblog.com/32267429/er-yb-yab-crystal-options
