The nonradiative transition charges Adhere to the formulation WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy gap. The nonradiative changeover prices of Er3+ show temperature dependence according to the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is https://knoxgkkki.ziblogs.com/33387071/the-5-second-trick-for-er-yb-yab-crystal
