THE 5-SECOND TRICK FOR ER:YB:YAB CRYSTAL

The nonradiative changeover rates Adhere to the formulation WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electrical power gap. The nonradiative transition charges of Er3+ show temperature dependence in line with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest premiums is complex
