The nonradiative transition rates Adhere to the system WNR = W (0) exp(-alphap), where p is the number of phonons matching the Power gap. The nonradiative transition prices of Er3+ exhibit temperature dependence in line with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative rest fees is https://erybyabcrystal75175.designertoblog.com/64429535/5-simple-statements-about-er-yb-yab-crystal-explained
