The nonradiative changeover fees Adhere to the system WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electricity hole. The nonradiative changeover rates of Er3+ exhibit temperature dependence according to the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is https://troyxcffd.suomiblog.com/a-review-of-er-yb-yab-crystal-50442807
