ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition charges Stick to the formula WNR = W (0) exp(-alphap), the place p is the number of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence according to the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative rest costs is intricate via th
