The nonradiative transition costs Keep to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy hole. The nonradiative transition costs of Er3+ show temperature dependence per the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace prices is intricate https://manuelmtvwv.oblogation.com/33950052/er-yb-yab-crystal-options
