The nonradiative changeover charges Adhere to the formulation WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the energy gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence in line with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative rest costs https://er-yb-yab-crystal30627.webdesign96.com/33654771/5-simple-techniques-for-er-yb-yab-crystal
