The nonradiative changeover premiums Stick to the system WNR = W (0) exp(-alphap), where p is the amount of phonons matching the Electricity gap. The nonradiative transition charges of Er3+ show temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest premiums is complex with https://erybyabcrystal97419.bloggactivo.com/32475344/the-best-side-of-er-yb-yab-crystal
