The nonradiative transition fees follow the formula WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the energy gap. The nonradiative transition rates of Er3+ exhibit temperature dependence in keeping with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation fees is https://glennb703lno8.wiki-racconti.com/user
