The nonradiative transition charges Adhere to the components WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Strength hole. The nonradiative changeover rates of Er3+ show temperature dependence according to the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation fees is challenging https://paulu257sqo8.plpwiki.com/user
