The nonradiative transition prices follow the components WNR = W (0) exp(-alphap), exactly where p is the amount of phonons matching the energy gap. The nonradiative transition premiums of Er3+ show temperature dependence per the multiphonon leisure principle. In Tm3+ the temperature dependence of nonradiative leisure rates is sophisticated through https://erybyabcrystal96283.iyublog.com/32324320/5-simple-statements-about-er-yb-yab-crystal-explained
