Abstract

Cerium oxide is commonly added to silicate glasses as an optical property modifier. In particular, UV absorption, decoloration via redox coupling, and resistance to radiation-induced darkening are influenced by the addition of this rare-earth oxide. However, the limited solubility and visible color of rare-earth oxides in silicate glasses prevent any further beneficial enhancement of properties which might result from increasing the CeO2 content. In contrast, rare-earth oxides are extremely soluble in phosphate glasses; for example, a binary cerium phosphate glass can incorporate up to 40 mol% CeO2. Moreover, since the UV absorption edge of the phosphate network is blue-shifted compared to the silicate network, the effect of the Ce3+ absorption band tail on yellow coloration can be minimized. In this study, glasses in the cerium aluminosilicophosphate system were synthesized and a variety of physical and optical properties were measured including: density, refractive index, glass transition temperature, hardness, fracture toughness, and the location of the UV absorption edge. At ∼9 mol% CeO2, these cerium aluminosilicophosphate glasses exhibit similar coloration to commercially available silicate glasses which contain ∼0.4 mol% CeO2. Semi-quantitative photoemission analysis of the Ce oxidation states showed insignificant differences in the Ce3+/Ce4+ ratio between the phosphate and silicate glass systems.
