The nonradiative changeover rates follow the formulation WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electrical power hole. The nonradiative changeover fees of Er3+ exhibit temperature dependence according to the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative rest costs is difficult https://juliar136mli5.lotrlegendswiki.com/user
