CONSIDERATIONS TO KNOW ABOUT ER:YB:YAB CRYSTAL

The nonradiative transition fees Keep to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy hole. The nonradiative changeover prices of Er3+ show temperature dependence consistent with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative rest rates is sophisticated from the exis
