WHAT DOES ER:YB:YAB CRYSTAL MEAN?

The nonradiative transition costs follow the formula WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Strength hole. The nonradiative transition premiums of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative peace charges is compli
