The nonradiative transition costs follow the formulation WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Strength gap. The nonradiative transition fees of Er3+ exhibit temperature dependence in step with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative rest costs is https://brucea692jlg5.webdesign96.com/profile
