The nonradiative transition costs Adhere to the formula WNR = W (0) exp(-alphap), in which p is the number of phonons matching the energy gap. The nonradiative changeover charges of Er3+ show temperature dependence consistent with the multiphonon peace concept. In Tm3+ the temperature dependence of nonradiative peace fees is https://chesterk914jhe4.gigswiki.com/user
