A SIMPLE KEY FOR ER:YB:YAB CRYSTAL UNVEILED

The nonradiative changeover prices Adhere to the method WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Strength hole. The nonradiative transition costs of Er3+ show temperature dependence in line with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative leisure prices is sophisticated bec
