THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative transition rates Adhere to the formulation WNR = W (0) exp(-alphap), where p is the amount of phonons matching the energy gap. The nonradiative transition premiums of Er3+ exhibit temperature dependence in line with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace charges is sophisticated fro
