ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover premiums Stick to the method WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Strength gap. The nonradiative transition fees of Er3+ show temperature dependence per the multiphonon leisure concept. In Tm3+ the temperature dependence of nonradiative relaxation fees is complex because of the exist
