The nonradiative transition charges Keep to the system WNR = W (0) exp(-alphap), where p is the number of phonons matching the Strength hole. The nonradiative changeover costs of Er3+ show temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative rest prices is challenging https://cicilc345kbn5.rimmablog.com/profile
