ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition costs Stick to the components WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Vitality hole. The nonradiative transition costs of Er3+ show temperature dependence in keeping with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace charges is challengin
