Spectroscopic properties of Pr3+ ions in Ge-In-S chalcogenide glasses

Popis výsledku v původním jazyce

Homogeneous and stable glasses from (80GeS220In2S3)100-x(Pr2S3)x system, where x=0-7, were prepared using conventional method (direct synthesis from elements in evacuated silica ampoules). In the transmission spectra of studied glasses, narrow absorptionbands, which were assigned to the intra-f electron transitions from the ground to higher energy levels of Pr3+ ions, are identified. The experimental values of oscillator strengths of individual electron transitions were calculated from the transmissionspectra. The Judd-Ofelt parameters ( 2, 4, 6) of Pr3+ ions in studied glasses were determined from the values of oscillator strengths. Absolute minimization as well as relative minimization fitting procedures using five or six transitions were applied for the determination of Judd-Ofelt parameters. Obtained values of Judd-Ofelt parameters are discussed in relation with different concentration of Pr3+ ions in studied glasses and with the type of calculation. The values of probabilities o
