The infrared emission spectra, measured under steady state conditions (CW excitation to the 4I9/2 erbium level), have allowed to obtain an experimental relationship linking the transfer (Yb3+ → Er3+) and back transfer (Er3+ → Yb3+) parameters. These measurements combined with the dynamics of the main emitting levels, measured under pulsed excitation to the 2H11/2 erbium level, have allowed the fully quantification of the energy transfer parameters. The obtained values, C25 = 5.5 × 10[sup]-18 cmsup3 s[sup]-1 (Yb3+ → Er3+), C[sub]52 = 1.5 x 10[sup]-18 cm[sup]3 s[sup]-1(Er[sup]3+ Yb[sup]3) and C[sub]27 = 7.6 x 10[sup]-18 cm[sup]3s[sup]-1 (up-conversion mechanism,estimated from the Judd-Ofelt analysis previously reported), can be used to predict the temporal evolution of the main luminescent emission bands. info:eu-repo/grantAgreement/ES/MICINN/PID2019-110632RB-I00 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 3.3 2023 OPTICS 33 / 119 = 0.277 2023 Q2 T1 0.589 2023 Atomic and Molecular Physics, and Optics 2023 Q2 Biophysics 2023 Q2 Condensed Matter Physics 2023 Q2 Chemistry (miscellaneous) 2023 Q2 Biochemistry 2023 Q3 6.7 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Lifante, Ginés Grima, Lorena Peña, José Ignacio Universidad de Zaragoza (orcid)0000-0003-2242-6822 Sola, Daniel (orcid)0000-0002-5998-2251 5001 065 Universidad de Zaragoza Dpto.
