The nonradiative changeover premiums Stick to the system WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Power hole. The nonradiative changeover prices of Er3+ show temperature dependence consistent with the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative rest costs is https://caroley467olf4.wikiparticularization.com/user
