5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative transition charges Adhere to the formula WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the Power gap. The nonradiative transition rates of Er3+ show temperature dependence consistent with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative peace rates is difficult by the exis
