Er:Yb:YAB Crystal - An Overview
The nonradiative transition rates Adhere to the system WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electrical power gap. The nonradiative changeover charges of Er3+ show temperature dependence according to the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest premiums is complicat
