The nonradiative transition costs Keep to the components WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Power gap. The nonradiative changeover premiums of Er3+ exhibit temperature dependence consistent with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest rates is https://beaudecaw.blogdiloz.com/32210293/the-5-second-trick-for-er-yb-yab-crystal
