The nonradiative transition charges follow the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Strength hole. The nonradiative transition costs of Er3+ show temperature dependence in line with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation costs is https://edwardh702eda2.thebindingwiki.com/user
