A SIMPLE KEY FOR ER:YB:YAB CRYSTAL UNVEILED

The nonradiative transition fees Stick to the formula WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electricity gap. The nonradiative transition premiums of Er3+ show temperature dependence in step with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace charges is sophisticated thro
