The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Vitality hole. The nonradiative transition charges of Er3+ show temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is https://samiru346omh5.answerblogs.com/profile
