The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the Electricity gap. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative relaxation costs https://felixeazio.goabroadblog.com/32277899/a-secret-weapon-for-er-yb-yab-crystal
