5 SIMPLE STATEMENTS ABOUT ER:YB:YAB CRYSTAL EXPLAINED

The nonradiative transition rates Adhere to the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Electricity hole. The nonradiative changeover charges of Er3+ show temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace premiums is sophisticated
