The nonradiative changeover charges follow the formulation WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Power hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence in line with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative relaxation costs is intricate https://danteqaayw.onesmablog.com/the-smart-trick-of-er-yb-yab-crystal-that-no-one-is-discussing-73677823
