The nonradiative transition prices Adhere to the system WNR = W (0) exp(-alphap), wherever p is the quantity of phonons matching the Vitality hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence in line with the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative leisure prices is https://zanderghdwo.total-blog.com/er-yb-yab-crystal-an-overview-58310469
