The nonradiative changeover rates follow the system WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Strength hole. The nonradiative transition rates of Er3+ exhibit temperature dependence in line with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest prices is https://erybyabcrystal46891.theisblog.com/35034184/helping-the-others-realize-the-advantages-of-er-yb-yab-crystal
