5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy hole. The nonradiative transition premiums of Er3+ exhibit temperature dependence per the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative leisure premiums is difficult with the exi
