The nonradiative changeover costs Keep to the method WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the energy hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence in line with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative leisure premiums is https://napoleonf791czy1.losblogos.com/profile
