5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative changeover premiums Stick to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy hole. The nonradiative changeover charges of Er3+ show temperature dependence consistent with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative leisure rates is intricate from the
