The nonradiative transition costs follow the formulation WNR = W (0) exp(-alphap), where p is the number of phonons matching the Electricity hole. The nonradiative changeover costs of Er3+ exhibit temperature dependence in line with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative peace premiums is challenging https://barryd691zaz4.activosblog.com/profile
