THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative transition rates Adhere to the method WNR = W (0) exp(-alphap), the place p is the number of phonons matching the energy hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence in line with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative rest charges is intricate through
