The nonradiative changeover costs follow the system WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure fees is challenging https://traudlq146nmj5.bloggip.com/profile
