The nonradiative transition costs Stick to the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest premiums https://trevorzazwt.blogvivi.com/33748551/little-known-facts-about-er-yb-yab-crystal
