ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Electrical power gap. The nonradiative transition premiums of Er3+ show temperature dependence in keeping with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest premiums is complex
