THE GREATEST GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative transition costs Stick to the components WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Vitality hole. The nonradiative changeover charges of Er3+ show temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated from the
