The nonradiative transition rates Stick to the formula WNR = W (0) exp(-alphap), exactly where p is the number of phonons matching the Electrical power hole. The nonradiative changeover charges of Er3+ show temperature dependence in step with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest https://rudyt369ahj7.homewikia.com/user
