The nonradiative transition fees Stick to the formula WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Power gap. The nonradiative changeover costs of Er3+ show temperature dependence in line with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative rest premiums https://erybyabcrystal96283.luwebs.com/33789003/a-simple-key-for-er-yb-yab-crystal-unveiled
