The nonradiative changeover prices Adhere to the formula WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Power hole. The nonradiative changeover premiums of Er3+ exhibit temperature dependence consistent with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation prices is https://er-yb-yab-crystal41728.blogdun.com/33922274/a-secret-weapon-for-er-yb-yab-crystal
