The nonradiative changeover rates follow the system WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Vitality gap. The nonradiative transition fees of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure fees is https://peteri888jwm7.vblogetin.com/profile
