The nonradiative transition costs Stick to the method WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the Strength gap. The nonradiative changeover premiums of Er3+ exhibit temperature dependence per the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative relaxation premiums is complex https://robertj701dax1.shopping-wiki.com/user
