ER:YB:YAB CRYSTAL FOR DUMMIES

The nonradiative transition rates Adhere to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Electricity gap. The nonradiative transition premiums of Er3+ show temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative leisure fees is difficult b
