The nonradiative transition premiums Keep to the method WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Strength gap. The nonradiative changeover premiums of Er3+ exhibit temperature dependence in step with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative leisure prices is https://erybyabcrystal84923.iyublog.com/33918523/rumored-buzz-on-er-yb-yab-crystal
