The nonradiative transition costs follow the system WNR = W (0) exp(-alphap), in which p is the number of phonons matching the energy hole. The nonradiative changeover charges of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest premiums is https://edwino055mkr9.levitra-wiki.com/user
