Abstract

Phosphate glasses with components of aluminum oxide and/or silica (“multi component” phosphate glasses) have been investigated for some time, as a means of increasing the chemical durability of phosphate glasses. For purposes of UV transmission, such multi-component glasses are typically not optimal, as they usually shift the absorption edge to the red. To compensate for this, fluorine is often added to such multi-component glasses, which complicates the fabrication due to safety requirements. However, BaO-CaO phosphate glasses have stability in the ambient adequate for many purposes. Furthermore, these glasses have the capacity for high doping expected from phosphate glasses, as well as UV transmission to about 295nm. We present here a brief look at the stability and Gd-doping of a BaO-CaO phosphate glass, of composition optimal for UV transmission.
