The nonradiative changeover rates Keep to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Electrical power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence consistent with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure fees is https://chancehjheb.blogdal.com/33584989/examine-this-report-on-er-yb-yab-crystal
