A Secret Weapon For Er:Yb:YAB Crystal
The nonradiative changeover charges Adhere to the formulation WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Vitality gap. The nonradiative transition charges of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest costs is intricat
