This research studied the preparation of luminescent glass aggregates prepared from soda-lime waste glass and strontium aluminate-based phosphors. The properties of the samples were determined by means of X-ray diffraction (XRD) technique, scanning electron microscopy (SEM), Archimedes’ method, and photoluminescence (PL) spectroscopy. It was found that the pore characteristics, density, and formation of crystallite phases in the glassy matrix depended on the phosphor content. The addition of fine phosphor powder tended to inhibit the glass crystallization and to reduce the apparent porosity of the aggregates. In general, the disadvantage of phosphors is their luminescent degradation under thermal attacks, which limits their use in applications involving high-temperature annealing. The phosphors, however, still had good luminescent properties and long-term stability with the sintering temperature as high as 750°C. The results indicated that the phosphors could be composited with glasses at high processing temperatures, enabling their widespread application.

用碱石灰废玻璃制备发光玻璃骨料

本研究以钠钙废玻璃和铝酸锶基荧光粉为原料制备发光玻璃骨料。通过X射线衍射（XRD）技术、扫描电子显微镜（SEM）、阿基米德法和光致发光（PL）光谱测定样品的性质。发现玻璃状基质中的孔隙特征、密度和微晶相的形成取决于磷光体含量。添加细荧光粉往往会抑制玻璃结晶并降低聚集体的表观孔隙率。通常，磷光体的缺点是它们在热攻击下的发光性能下降，这限制了它们在涉及高温退火的应用中的使用。然而，荧光粉，在高达750℃的烧结温度下仍具有良好的发光性能和长期稳定性。结果表明，荧光粉可以在高加工温度下与玻璃复合，使其得到广泛应用。
