The nonradiative changeover rates Adhere to the formulation WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electricity gap. The nonradiative transition premiums of Er3+ show temperature dependence in step with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation charges https://er-yb-yab-crystal52840.blog-gold.com/41731470/what-does-er-yb-yab-crystal-mean
