The nonradiative transition rates follow the system WNR = W (0) exp(-alphap), in which p is the number of phonons matching the energy gap. The nonradiative changeover prices of Er3+ exhibit temperature dependence in keeping with the multiphonon peace principle. In Tm3+ the temperature dependence of nonradiative rest fees is https://lanejmlie.bloggactivo.com/32595021/the-ultimate-guide-to-er-yb-yab-crystal
