The nonradiative changeover fees Adhere to the system WNR = W (0) exp(-alphap), where p is the number of phonons matching the Electrical power gap. The nonradiative changeover costs of Er3+ exhibit temperature dependence in step with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative peace charges https://er-yb-yab-crystal42962.blogsuperapp.com/35394735/er-yb-yab-crystal-an-overview
