The nonradiative transition rates follow the formulation WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electricity gap. The nonradiative transition rates of Er3+ show temperature dependence according to the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative leisure charges is challenging via https://fanr147vuw3.mycoolwiki.com/user
