The nonradiative transition fees Stick to the system WNR = W (0) exp(-alphap), where by p is the number of phonons matching the Vitality gap. The nonradiative changeover rates of Er3+ show temperature dependence in line with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative peace rates https://leopoldok035oor9.wikijournalist.com/user
