5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative transition fees follow the components WNR = W (0) exp(-alphap), exactly where p is the number of phonons matching the energy gap. The nonradiative changeover prices of Er3+ show temperature dependence in line with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative rest charges is intricate with t
