FACTS ABOUT ER:YB:YAB CRYSTAL REVEALED

The nonradiative transition prices Keep to the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Power hole. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest costs is complex through the exist
