The nonradiative transition costs Keep to the components WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Strength hole. The nonradiative transition costs of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative rest prices https://er-yb-yab-crystal39516.targetblogs.com/33592067/the-basic-principles-of-er-yb-yab-crystal
