The optical absorption spectra of an irradiated zirconium‐barium‐lanthanum aluminum‐ lithium fluoride glass prepared with 1 wt% BaC12 were resolved into Gaussian bands identified as the V k , and V H centers, Zr 3+ , and two bands associated with Cl, i.e., FCl − at 4.78 eV and Cl − 2 at 3.90 eV. These latter bands are more thermally stable than the VH and V, trapped hole centers, persisting to 450 and 550 K, respectively.
