The nonradiative transition costs Keep to the system WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Strength hole. The nonradiative transition costs of Er3+ exhibit temperature dependence in line with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest fees https://jimiv368utq9.losblogos.com/profile
