THE DEFINITIVE GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative changeover charges follow the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Vitality hole. The nonradiative transition charges of Er3+ show temperature dependence in step with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is complicated through
