The nonradiative transition costs Stick to the system WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Power hole. The nonradiative changeover charges of Er3+ show temperature dependence in step with the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative rest premiums https://johnm790ayv1.techionblog.com/profile
