FACTS ABOUT ER:YB:YAB CRYSTAL REVEALED

The nonradiative changeover rates Stick to the components WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the energy gap. The nonradiative changeover prices of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative peace prices is sophisticated from the e
