The nonradiative transition charges Adhere to the method WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy hole. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest premiums is https://rowanfhgda.theideasblog.com/33783723/er-yb-yab-crystal-an-overview
