WHAT DOES ER:YB:YAB CRYSTAL MEAN?

The nonradiative transition fees Keep to the formula WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the energy gap. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace charges is sophisticated from the ex
