The nonradiative changeover rates follow the method WNR = W (0) exp(-alphap), the place p is the quantity of phonons matching the Electrical power gap. The nonradiative transition premiums of Er3+ exhibit temperature dependence in step with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative relaxation premiums https://heraclitusi936twy2.buscawiki.com/user
