WHAT DOES ER:YB:YAB CRYSTAL MEAN?

The nonradiative transition prices follow the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Strength gap. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative rest costs is sophisticated because of the exi
