A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative changeover premiums Stick to the formulation WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Electricity hole. The nonradiative changeover costs of Er3+ show temperature dependence consistent with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest fees is sophisti
