THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative changeover charges Keep to the formulation WNR = W (0) exp(-alphap), where by p is the volume of phonons matching the Electricity gap. The nonradiative transition premiums of Er3+ exhibit temperature dependence in keeping with the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is sophist
