The nonradiative changeover costs follow the formulation WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Electricity gap. The nonradiative transition charges of Er3+ show temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is complex https://nielsoni802fda3.thecomputerwiki.com/user
