The nonradiative transition charges Stick to the method WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the Power gap. The nonradiative changeover costs of Er3+ show temperature dependence in line with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative leisure costs https://er-yb-yab-crystal40639.shotblogs.com/the-greatest-guide-to-er-yb-yab-crystal-47214326
