The nonradiative changeover fees Keep to the system WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Electrical power hole. The nonradiative changeover rates of Er3+ show temperature dependence in keeping with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative relaxation https://johnt258wwu0.blog2freedom.com/profile
