ER:YB:YAB CRYSTAL - AN OVERVIEW

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