THE GREATEST GUIDE TO ER:YB:YAB CRYSTAL

The nonradiative changeover premiums Keep to the formula WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electrical power gap. The nonradiative transition rates of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative relaxation fees is i
