CONSIDERATIONS TO KNOW ABOUT ER:YB:YAB CRYSTAL

The nonradiative changeover rates Stick to the method WNR = W (0) exp(-alphap), where p is the number of phonons matching the Vitality gap. The nonradiative transition charges of Er3+ show temperature dependence in step with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest charges is sophisticated by the exist
