Modern technology largely depends on mastery of materials. Functional glasses and glass-ceramics are important for a range of technological applications by enabling fabrication of a range of devices in the sectors of energy, visual displays, health care, nuclear, defence, and space. In doped glasses there is a challenge to achieve the required functional centres due to limited control of dopant sites in high temperature melts. Sol-gels offer greater scope to control the local atomic environment but need to be thermally processed to high temperatures to eliminate residues and porosity. Glass ceramics are not usually transparent, and are not able to incorporate a range of functional nanocrystals due to the difficulty of controlling the crystallisation process. This project will create an exciting new generation of functional materials through oxide nanocrystal doping of glasses. This approach will be demonstrated by creating a new type of glass for optical applications. The final aim is to succeed in combining properties which are found separately in existing categories of glass ceramics, doped glasses, and sol-gels, such as bulk density, transparency, and a variety of functional nanocomponents.

现代技术在很大程度上取决于材料的掌握。功能性眼镜和玻璃陶瓷对于一系列技术应用很重要，可以通过在能源，视觉展示，医疗保健，核，防御和空间领域制造一系列设备。在掺杂的眼镜中，由于高温熔体中对掺杂位点的控制有限，要达到所需的功能中心存在挑战。 Sol-Gels提供了更大的范围来控制局部原子环境，但需要热处理高温以消除残基和孔隙率。玻璃陶瓷通常不透明，并且由于难以控制结晶过程，因此无法结合一系列功能性纳米晶体。该项目将通过氧化物纳米晶体掺杂玻璃创造令人兴奋的新一代功能材料。通过为光学应用创建一种新型的玻璃来证明这种方法。最终目的是成功地结合了在现有类别的玻璃陶瓷，掺杂玻璃和溶胶凝胶类别中分别发现的性能，例如散装密度，透明度和各种功能性纳米组件。
