The nonradiative changeover charges Adhere to the components WNR = W (0) exp(-alphap), in which p is the amount of phonons matching the Power gap. The nonradiative changeover charges of Er3+ show temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative rest rates is https://atecaa603lnp8.spintheblog.com/profile
