The nonradiative changeover premiums follow the components WNR = W (0) exp(-alphap), exactly where p is the number of phonons matching the Vitality gap. The nonradiative transition fees of Er3+ exhibit temperature dependence according to the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is complicated https://mitchw358tro8.governor-wiki.com/user
