ER:YB:YAB CRYSTAL FOR DUMMIES

The nonradiative changeover prices Stick to the formulation WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Electricity gap. The nonradiative transition premiums of Er3+ show temperature dependence per the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated
