The nonradiative transition costs Stick to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the energy gap. The nonradiative changeover prices of Er3+ show temperature dependence in line with the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative rest costs https://wardj702eby2.oneworldwiki.com/user
