Toward a Structural Model for the Aluminum Tellurite Glass System (2020)
Journal Article
Barney, E., Laorodphan, N., Mohd-Noor, F., Holland, D., Kemp, T., Iuga, D., & Dupree, R. (2020). Toward a Structural Model for the Aluminum Tellurite Glass System. Journal of Physical Chemistry C, 124(37), 20516–20529. https://doi.org/10.1021/acs.jpcc.0c04342

Neutron diffraction, 27Al MAS NMR, and 27Al Double Quantum MAS NMR results are presented and analyzed to determine the local environments of the cations in a series of aluminum tellurite glasses. Total scattering results show that, within a maximum T... Read More about Toward a Structural Model for the Aluminum Tellurite Glass System.

Experimental photoluminescence and lifetimes at wavelengths including beyond 7 microns in Sm3+-doped selenide-chalcogenide glass fibers (2020)
Journal Article
Crane, R. W., Sojka, Ł., Furniss, D., Nunes, J., Barney, E., Farries, M. C., …Seddon, A. B. (2020). Experimental photoluminescence and lifetimes at wavelengths including beyond 7 microns in Sm3+-doped selenide-chalcogenide glass fibers. Optics Express, 28(8), 12373-12384. https://doi.org/10.1364/oe.383033

1000 ppmw Sm3+-doped Ge19.4Sb9.7Se67.9Ga3 atomic % chalcogenide bulk glass and unstructured fiber are prepared. Near- and mid-infrared absorption spectra of the bulk glass reveal Sm3+ electronic absorption bands, and extrinsic vibrational absorption...
