The nonradiative transition rates Stick to the formula WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Electrical power gap. The nonradiative transition rates of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative rest https://er-yb-yab-crystal52839.blogaritma.com/31486403/the-definitive-guide-to-er-yb-yab-crystal
