ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition charges Keep to the formula WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative relaxation costs is complicated
