Abstract:

The report describes work done in areas of glass science. X-ray and neutron diffraction studies have demonstrated a degree of ordering in glassy SiO2, while experimental and theoretical studies of radiation-induced defects in this important material have been advanced considerably. The first observation has been made of free carrier optical absorption in semiconducting chalcogenide glasses and the existence of a new fundamental defect center in alkali borate glasses has been confirmed. A potential new laser glass has been formulated and optimized with respect to immunity from platinum contamination efforts to prepare and test large batches have been initiated.
