THE GREATEST GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative transition premiums Keep to the system WNR = W (0) exp(-alphap), wherever p is the quantity of phonons matching the energy gap. The nonradiative transition rates of Er3+ show temperature dependence in keeping with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative leisure charges is complicated because of
