NOT KNOWN DETAILS ABOUT ER:YB:YAB CRYSTAL

The nonradiative changeover charges Keep to the method WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Electrical power gap. The nonradiative transition prices of Er3+ show temperature dependence in step with the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative leisure rates is complicated becaus
