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对材料的掌握。功能玻璃和微晶玻璃能够制造能源、视觉显示器、医疗保健、核、国防和空间等领域的一系列设备，因此对一系列技术应用非常重要。在掺杂玻璃中，由于对高温熔体中掺杂位置的控制有限，实现所需的功能中心是一个挑战。溶胶-凝胶提供了更大的范围来控制当地的原子环境，但需要将其热处理到高温以消除残留物和孔洞。微晶玻璃通常不是透明的，而且由于难以控制晶化过程，无法包含一系列功能纳米晶体。该项目将通过氧化物纳米晶掺杂玻璃来创造令人兴奋的新一代功能材料。这种方法将通过创造一种用于光学应用的新型玻璃来演示。最终目标是成功地将现有类别的微晶玻璃、掺杂玻璃和溶胶-凝胶中单独存在的特性结合在一起，如体积密度、透明度和各种功能纳米组件。
