The nonradiative changeover premiums Keep to the formulation WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Electrical power gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence consistent with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest rates https://andersondatld.pointblog.net/facts-about-er-yb-yab-crystal-revealed-79248674
