The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electricity hole. The nonradiative transition premiums of Er3+ exhibit temperature dependence consistent with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative leisure rates is challenging https://er-yb-yab-crystal39517.dailyhitblog.com/38603708/er-yb-yab-crystal-for-dummies
