The nonradiative transition charges follow the method WNR = W (0) exp(-alphap), where p is the number of phonons matching the Electricity gap. The nonradiative transition premiums of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure rates is challenging https://claytoncejmg.aioblogs.com/86384377/the-best-side-of-er-yb-yab-crystal
