Judd-Ofelt analysis of Pr3+ ions in fluoroindate glasses: Influence of odd third order intensity parameters

In this work an analysis of the Judd-Ofelt phenomenological Omega(lambda) intensity parameters for the pr(3+) ion in fluoroindate glass is made. Different Pr3+ concentrations, namely 1, 2, 3 and 4 mol% are used. The experimental oscillator strengths have been determined from the absorption spectra. A consistent set of parameters is obtained only with the inclusion of odd rank third order intensity parameters and if the band at 21470 cm(-1) is assigned to the H-3(4)-->P-3(1) transition and the I-1(6) component is incorporated in the H-3(4)-->P-3(2) transition at 22 700 cm(-1).
