A SIMPLE KEY FOR ER:YB:YAB CRYSTAL UNVEILED

The nonradiative transition charges Adhere to the components WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the energy hole. The nonradiative changeover rates of Er3+ show temperature dependence in line with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative leisure fees is sophisticated from
