The nonradiative transition prices Adhere to the formulation WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Electricity gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence according to the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative relaxation charges is complicated https://landenxwxwr.jaiblogs.com/60189484/the-smart-trick-of-er-yb-yab-crystal-that-no-one-is-discussing
