The nonradiative transition costs Stick to the formulation WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Electricity hole. The nonradiative changeover fees of Er3+ show temperature dependence in step with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative rest charges https://shanejpqrr.loginblogin.com/42274907/little-known-facts-about-er-yb-yab-crystal
