The nonradiative transition rates Stick to the formula WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Power hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure fees is https://beaudgfda.tusblogos.com/33339375/details-fiction-and-er-yb-yab-crystal
