The nonradiative transition premiums follow the method WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the energy hole. The nonradiative changeover premiums of Er3+ show temperature dependence according to the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative relaxation costs is challenging https://benjaminf578pkf4.thekatyblog.com/profile
