The nonradiative changeover costs Stick to the formula WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Electricity gap. The nonradiative changeover costs of Er3+ show temperature dependence in keeping with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative rest rates is https://er-yb-yab-crystal52739.angelinsblog.com/32376546/5-easy-facts-about-er-yb-yab-crystal-described
