5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

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