WHAT DOES ER:YB:YAB CRYSTAL MEAN?

The nonradiative transition costs Stick to the components WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy gap. The nonradiative changeover prices of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is complex with the exi
