The nonradiative transition costs Stick to the components WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is https://er-yb-yab-crystal52739.ka-blogs.com/86441586/the-2-minute-rule-for-er-yb-yab-crystal
