A SIMPLE KEY FOR ER:YB:YAB CRYSTAL UNVEILED

The nonradiative changeover fees Adhere to the method WNR = W (0) exp(-alphap), where p is the number of phonons matching the Electricity hole. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative peace rates is sophisticated through the e
