The nonradiative transition premiums follow the formula WNR = W (0) exp(-alphap), exactly where p is the number of phonons matching the Electricity hole. The nonradiative transition rates of Er3+ show temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative rest premiums is sophisticated https://eye-safe-laser-crystal30627.ttblogs.com/profile
