5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative changeover rates Stick to the system WNR = W (0) exp(-alphap), where p is the amount of phonons matching the Power hole. The nonradiative transition fees of Er3+ show temperature dependence in line with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative rest charges is intricate by the existence of
