The nonradiative transition charges Stick to the formulation WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Power hole. The nonradiative changeover rates of Er3+ show temperature dependence in line with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative peace charges https://er-yb-yab-crystal52849.vblogetin.com/38990959/5-easy-facts-about-er-yb-yab-crystal-described
