The nonradiative transition costs Stick to the components WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the energy gap. The nonradiative changeover prices of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative leisure premiums is https://zachg702fdb3.activablog.com/profile
