Er:Yb:YAB Crystal - An Overview
The nonradiative changeover charges follow the system WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electricity hole. The nonradiative transition charges of Er3+ show temperature dependence in line with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticate
