ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition rates Stick to the components WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Strength gap. The nonradiative transition premiums of Er3+ exhibit temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative leisure costs is challenging through the e
