CONSIDERATIONS TO KNOW ABOUT ER:YB:YAB CRYSTAL

The nonradiative transition costs Stick to the components WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the energy gap. The nonradiative transition fees of Er3+ exhibit temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative peace rates is challenging via the existence of
