ER:YB:YAB CRYSTAL FOR DUMMIES

The nonradiative transition costs follow the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Vitality gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence per the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative rest charges is complicated from the existence of se
