ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition premiums Stick to the components WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Strength hole. The nonradiative transition costs of Er3+ show temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation prices is challenging via the ex
