The nonradiative changeover premiums follow the components WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Electricity gap. The nonradiative changeover costs of Er3+ show temperature dependence in keeping with the multiphonon leisure concept. In Tm3+ the temperature dependence of nonradiative rest prices is https://douglasu257sqo7.prublogger.com/profile
