The nonradiative changeover fees Stick to the formula WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electrical power gap. The nonradiative changeover costs of Er3+ exhibit temperature dependence per the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation premiums is difficult https://geronimos246onm7.wikilowdown.com/user
