5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative changeover rates Adhere to the system WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Power hole. The nonradiative transition costs of Er3+ show temperature dependence consistent with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative peace rates is complex from the ex
