Abstract
Effect of the substitution of Y2O3 for Al2O3 in the phosphate glass, Nd3+: P2O5-Al2O3-ZnO, on glass structure and properties are investigated. With Al2O3 replaced by Y2O3, the decrease in coefficient of thermal expansion and Young's Modulus, as well as the increase in fracture toughness, lead to a significant improvement in thermal shock resistance. According to the NMR and Raman spectra, changes in the coordination of Al3+ from P-O-Al (6) bonds to P-O-Al (4) bonds and glass structure occur, resulting in inflection points in properties. Moreover, the fluorescence properties are measured and analyzed. The relationship between glass structure and physical (ρ, Tg, α), mechanical (E, HV, KIC), and optical properties (n, σems, Δλeff, λP) are explained.
期刊介绍：
The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid.
In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
