The nonradiative changeover rates Adhere to the formulation WNR = W (0) exp(-alphap), where p is the amount of phonons matching the energy gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence consistent with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is intricate https://erybyabcrystal97306.full-design.com/top-latest-five-er-yb-yab-crystal-urban-news-75602871
