5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative changeover charges Stick to the method WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Electrical power gap. The nonradiative changeover prices of Er3+ show temperature dependence in line with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is complicated w
