The nonradiative transition rates Adhere to the formula WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Vitality gap. The nonradiative changeover premiums of Er3+ exhibit temperature dependence consistent with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative peace premiums is sophisticated https://fridad680ayw0.bimmwiki.com/user
