The nonradiative changeover fees follow the formula WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Strength gap. The nonradiative changeover premiums of Er3+ exhibit temperature dependence in step with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative peace rates is https://ambrosev470fik7.wikiinside.com/user
