The nonradiative transition rates follow the formulation WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Vitality gap. The nonradiative changeover prices of Er3+ show temperature dependence according to the multiphonon leisure concept. In Tm3+ the temperature dependence of nonradiative relaxation charges is challenging https://paulv357rpm7.webbuzzfeed.com/profile
