The nonradiative changeover costs follow the system WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the energy gap. The nonradiative transition costs of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation prices is https://jasonp146uxz3.wizzardsblog.com/profile
