Abstract

The Judd-Ofelt parameters (W2, W4, W6) of Pr3+ ions in ((GeS2)80(In2S3)20)100-x(Pr2S3)x glasses (x=0.5-7) were determined from the values of experimentally obtained electric dipole oscillator strengths of intra-f configuration electron transitions. Absolute as well as normalized minimization fitting procedures using five or six transitions were applied for the determination of Judd-Ofelt parameters. Obtained values of Judd-Ofelt parameters, root mean square deviations, and other optical parameters (probabilities of spontaneous radiative electron transitions, emission cross-sections) are discussed in relation with different concentration of Pr3+ ions in studied glasses and with the type of calculation..
