Abstract

New rare-earth-rich fluoroarsenate glasses are synthesized in the M₂O, As₂O₅, BaF₂, YF₃ system, with M equals Na or K. The glass-forming region is remarkably large in the Na₄As₂O₇, BaF₂, YF₃ system. Stable compositions with rare-earth fluoride concentration as high as 40 mol% can be synthesized. Thermal and optical properties are given for these new glasses. The behavior of neodymium ions in this new host is investigated in terms of Judd-Ofelt calculations, emission and excitation spectroscopy, and lifetime measurements as a function of temperature and concentration.
