The nonradiative transition fees follow the components WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Power hole. The nonradiative transition fees of Er3+ show temperature dependence in step with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative rest fees is https://aeschylusx368tsq8.bloggazzo.com/profile
