The nonradiative changeover premiums Stick to the system WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Electricity gap. The nonradiative changeover costs of Er3+ show temperature dependence in line with the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative leisure rates https://erybyabcrystal84062.blogdosaga.com/33188315/5-easy-facts-about-er-yb-yab-crystal-described
