The nonradiative changeover costs Stick to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power gap. The nonradiative transition prices of Er3+ show temperature dependence in keeping with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative leisure https://titusoqdhi.blogars.com/32076885/details-fiction-and-er-yb-yab-crystal
