WHAT DOES ER:YB:YAB CRYSTAL MEAN?

The nonradiative changeover rates Adhere to the method WNR = W (0) exp(-alphap), exactly where p is the amount of phonons matching the energy gap. The nonradiative transition premiums of Er3+ show temperature dependence per the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative leisure costs is challenging via the existence
