Er:Yb:YAB Crystal for Dummies
The nonradiative transition fees Adhere to the system WNR = W (0) exp(-alphap), the place p is the number of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence per the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated by the existence
