5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative transition charges Stick to the formulation WNR = W (0) exp(-alphap), where by p is the number of phonons matching the energy hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence in line with the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative leisure rates is difficult by
