NOT KNOWN DETAILS ABOUT ER:YB:YAB CRYSTAL

The nonradiative transition premiums Keep to the formulation WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power hole. The nonradiative changeover costs of Er3+ show temperature dependence in step with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is co
