THE GREATEST GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative changeover premiums Keep to the formulation WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Electricity gap. The nonradiative changeover prices of Er3+ show temperature dependence in line with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace rates is chal
