The nonradiative changeover fees Keep to the system WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Vitality hole. The nonradiative transition costs of Er3+ show temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest costs is complicated https://peterq146ool6.vigilwiki.com/user
