The nonradiative transition costs Stick to the components WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Strength hole. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest premiums https://erickklmmk.fare-blog.com/33440715/top-guidelines-of-er-yb-yab-crystal
