Inverse Judd–Ofelt Formalism Based on Radiative Lifetime for Comparative Spectroscopy of RE³⁺ Ions in Glass

This work shows that inverse Judd–Ofelt (JO) analysis of relative absorption spectra, anchored by a single lifetime, provides JO parameters and radiative rates without absolute calibration. The method is applied to Er³⁺, Dy³⁺, and Sm<sup>3+</sup...
