The nonradiative transition costs Stick to the formulation WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the energy hole. The nonradiative transition premiums of Er3+ exhibit temperature dependence per the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation premiums is challenging https://josuexyzzw.like-blogs.com/32929434/rumored-buzz-on-er-yb-yab-crystal
