The nonradiative transition charges Adhere to the system WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Power gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence according to the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure rates is https://erybyabcrystal36578.canariblogs.com/er-yb-yab-crystal-an-overview-49634719
