FACTS ABOUT ER:YB:YAB CRYSTAL REVEALED

The nonradiative transition fees Keep to the system WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Vitality hole. The nonradiative changeover charges of Er3+ exhibit temperature dependence in line with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest costs is complex because of
