The nonradiative transition rates Stick to the system WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Electrical power hole. The nonradiative changeover premiums of Er3+ show temperature dependence in line with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative leisure https://er-yb-yab-crystal62840.bloggip.com/33360674/the-2-minute-rule-for-er-yb-yab-crystal
