WHAT DOES ER:YB:YAB CRYSTAL MEAN?

The nonradiative changeover costs Keep to the formula WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Strength hole. The nonradiative changeover prices of Er3+ show temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative leisure fees is difficult with the e
