Optical transition probabilities and compositional dependence of Judd-Ofelt parameters of Er3+ ions in fluoroindate glass

TL;DR: From transient measurements it was concluded that for lightly doped samples the green upconverted emission is originated due to both processes ESA and ET, however, for heavily doping samples ET is the dominant process.

TL;DR: In this paper, the results of absorption, emission and fluorescence lifetime measurements (for the 4 I 13/2 → 4 I 15/2 transition) are presented for lead fluoroborate glasses doped with different concentrations of Er 3+ varying from 0.22 x 10 20 ions/cm 3 to 5.96 x 1020 ions/ cm 3, the calculated Judd-Ofelt parameters are: Ω 2 = (1.2 ± 0.1) × 10 -20 cm 2, Ω 4 = (0.59 + 0.04) x 10 -

TL;DR: In this article, the Czochralski technique has been used to determine the energy position of 32, 39 and 36 −Pr3+ Stark levels in NBW, NBMo and LBMo, respectively.

TL;DR: In this paper, the upconversions observed due to energy transfer in Er3+ doped bismuth glass have been studied and explained, and the effect of temperature on the luminescence intensity of the bands has been monitored and inferred that these may be used to sense the temperature with appreciable sensitivity.

TL;DR: In this article, the transition probability of pure-electronic electric dipole transitions between levels of the 4-fluorescence configuration perturbed by a static crystalline field is treated.

TL;DR: Gerhard Dieke as mentioned in this paper was involved in the Manhattan Project as a spectroscopist studying the uranyl salts and this led him into a detailed study of the absorption and fluorescence spectra of the rare earths which commenced in 1953 and ended with his untimely death.

TL;DR: In this article, it was shown that the absorption lines of the lanthanides that are peculiarly sensitive to changes in the ligands are consistent with the selection rules for quadrupole radiation within the 4f shell.
