The nonradiative changeover charges Keep to the formula WNR = W (0) exp(-alphap), where p is the number of phonons matching the Electrical power gap. The nonradiative transition fees of Er3+ exhibit temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace charges is https://erybyabcrystal96284.blogsvila.com/33422844/er-yb-yab-crystal-can-be-fun-for-anyone
