The nonradiative transition fees Keep to the formulation WNR = W (0) exp(-alphap), wherever p is the quantity of phonons matching the energy gap. The nonradiative transition fees of Er3+ show temperature dependence consistent with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative leisure fees is intricate https://irvingv368wbi7.wikinewspaper.com/user
