Abstract
Optically active glass-ceramics (GC) with the low-phonon phases of fluorides, doped with Er3+ was studied. Glass based on SiO 2-Al2O3-Na2F2-Na 2O-GdF3-BaO system was obtained. Dopant were introduced to the glass in an amount of 0.01 mol Er2O3 per 1 mol of glass. DTA/DSC study shows multi-stage crystallization. XRD identification of obtained phases did not confirm the presence of pure GdF3 phase. Instead of that ceramization process led to formation of NaGdF4 and BaGdF5. The structural changes were studied using FT-IR spectroscopic method. The study of luminescence of the samples confirmed that optical properties of the obtained GC depend on crystallizing phases during ceramization. Time resolved spectroscopy of Er-doped glass showed the 3 and 8 times increase of lifetime of emission from 4S3/2 and 4F9/2 states, respectively. It confirms the erbium ions have ability to locate in the low phonon gadolinium-based crystallites. The results give possibility to obtain a new material for optoelectronic application. © 2014 Elsevier B.V. All rights reserved.
