The 5-Second Trick For Er:Yb:YAB Crystal
The nonradiative transition premiums Keep to the components WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Electrical power gap. The nonradiative changeover premiums of Er3+ show temperature dependence in keeping with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace fees is complic
