The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Strength hole. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is https://popev481cys8.izrablog.com/profile
