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 21 470 cm-1 is assigned to the 3H4 → 3P1 transition and the 1I6 component is incorporated in the 3H4 → 3P2 transition at 22 700 cm-1.315-320engAbsorption spectroscopyApproximation theoryGlass transitionIonsLight emissionMathematical modelsOptical glassPraseodymiumFluoroindate glassJudd-Ofelt theoryOdd third order intensity parametersOscillator strengthPraseodymium ionsLight absorptionArtigo10.1016/S0022-3093(97)00014-8WOS:A1997XG22100057Acesso restrito2-s2.0-00311651392998503841917815
