NOT KNOWN DETAILS ABOUT ER:YB:YAB CRYSTAL

The nonradiative changeover prices follow the system WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electricity gap. The nonradiative transition prices of Er3+ show temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative rest costs is complex from the
