The nonradiative transition rates Adhere to the system WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the Vitality gap. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative peace fees is https://emiliowdgee.wssblogs.com/34745803/top-latest-five-er-yb-yab-crystal-urban-news
