The nonradiative transition prices follow the formulation WNR = W (0) exp(-alphap), where p is the number of phonons matching the Vitality hole. The nonradiative changeover premiums of Er3+ exhibit temperature dependence consistent with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest rates is complicated with https://er-yb-yab-crystal51839.get-blogging.com/33679098/the-basic-principles-of-er-yb-yab-crystal
