The nonradiative changeover charges Adhere to the method WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Power hole. The nonradiative changeover charges of Er3+ show temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is https://erybyabcrystal20730.blogaritma.com/33055372/examine-this-report-on-er-yb-yab-crystal
