The nonradiative transition costs follow the method WNR = W (0) exp(-alphap), exactly where p is the amount of phonons matching the Electrical power hole. The nonradiative changeover charges of Er3+ show temperature dependence in step with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative peace premiums https://knoxzzatm.blogrenanda.com/39353279/a-secret-weapon-for-er-yb-yab-crystal
