The nonradiative changeover costs Keep to the method WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the energy gap. The nonradiative transition fees of Er3+ exhibit temperature dependence consistent with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest costs is https://emilyy580zus0.wikiexcerpt.com/user
