The nonradiative transition charges Stick to the system WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence according to the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative relaxation premiums is https://edwinfgecy.activoblog.com/35541053/the-smart-trick-of-er-yb-yab-crystal-that-no-one-is-discussing
