The nonradiative transition fees follow the system WNR = W (0) exp(-alphap), the place p is the number of phonons matching the energy hole. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative leisure premiums is https://cordellb848esv0.webbuzzfeed.com/profile
