ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative changeover premiums Adhere to the method WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electrical power gap. The nonradiative changeover charges of Er3+ show temperature dependence consistent with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure fees is cha
