Zusammenfassung:(Li O) (SrO) (Nd O ) (B O ) (Gd O ) , where = 0, 3, 5, 7, and 10 mol%, glass was melt-quenched to test it as a laser source in the near-infrared (NIR) region. The structural modification, absorption spectra, Judd-Ofelt (J-O) parameters, luminescence spectra, radiative laser parameters, lifetimes, XRD, and FTIR spectra were studied. Luminescence spectra excited at = 584 nm revealed the highest intensity peak at 1073 nm due to the transition of F → I . An important phenomenon of concentration quenching was observed and optimized luminescence was achieved with the sample having the concentration = 07 mol%. The lifetimes of the donor and acceptor and energy transfer from gadolinium to neodymium were obtained from the luminescence decay kinetics. The findings show that Nd-doped Gd O -modified glass materials have potential as NIR laser sources.
