The nonradiative transition rates Stick to the components WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the energy gap. The nonradiative changeover premiums of Er3+ exhibit temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative rest fees is intricate https://harryi813iih5.blogpixi.com/profile
