The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative changeover fees of Er3+ show temperature dependence in line with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative peace https://erybyabcrystal85173.tblogz.com/er-yb-yab-crystal-an-overview-46893035
