The nonradiative transition charges Stick to the system WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the energy gap. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation charges https://alexisuvbkh.win-blog.com/13571783/a-secret-weapon-for-er-yb-yab-crystal
