The nonradiative transition rates Stick to the formulation WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the Power hole. The nonradiative changeover fees of Er3+ show temperature dependence per the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative peace charges is challenging from https://cashbdcfc.blogdal.com/33601310/what-does-er-yb-yab-crystal-mean
