The nonradiative changeover costs Stick to the components WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the Electricity 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 costs https://erickcecax.bloggazzo.com/32284110/the-5-second-trick-for-er-yb-yab-crystal
