The nonradiative changeover charges follow the components WNR = W (0) exp(-alphap), exactly where p is the amount of phonons matching the Strength gap. The nonradiative changeover costs of Er3+ show temperature dependence in step with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative leisure charges is https://miltonl258wyr8.wikijournalist.com/user
