FACTS ABOUT ER:YB:YAB CRYSTAL REVEALED

The nonradiative transition prices Keep to the components WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Electricity gap. The nonradiative transition rates of Er3+ show temperature dependence per the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative rest fees is difficult via the existence of se
