The nonradiative transition costs Stick to the components WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Strength hole. The nonradiative changeover charges of Er3+ exhibit temperature dependence consistent with the multiphonon peace idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is intricate https://er-yb-yab-crystal91356.bloggactif.com/36132560/top-guidelines-of-er-yb-yab-crystal
