NOT KNOWN DETAILS ABOUT ER:YB:YAB CRYSTAL

The nonradiative changeover prices follow the method WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Strength hole. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest premiums is complex because of the exi
