The nonradiative changeover charges follow the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Vitality hole. The nonradiative transition costs of Er3+ show temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative leisure fees is difficult because https://donovanvacbx.oblogation.com/32384653/5-simple-statements-about-er-yb-yab-crystal-explained
