The nonradiative changeover costs Keep to the system WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electrical power gap. The nonradiative changeover charges of Er3+ exhibit temperature dependence consistent with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation fees is https://fredf791dda2.blogrenanda.com/profile
