The nonradiative changeover costs follow the system WNR = W (0) exp(-alphap), the place p is the number of phonons matching the energy hole. The nonradiative transition premiums of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative peace fees is https://emilyw350fin8.buyoutblog.com/profile
