THE BEST SIDE OF ER:YB:YAB CRYSTAL

The nonradiative transition premiums Stick to the components WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electricity gap. The nonradiative transition costs of Er3+ show temperature dependence in line with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative peace charges is sophisticat
