The nonradiative changeover fees Stick to the formula WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electrical power gap. The nonradiative transition rates of Er3+ exhibit temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is intricate by t
