000123851 5203_ $$aThe resonant cross relaxation processes between Yb3+ and Er3+ ions in calcium alumino-silicate glasses have been quantified under selective Er3+ excitation. 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.
