ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition fees Keep to the formulation WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Power gap. The nonradiative changeover charges of Er3+ show temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated from th
