通过传统的熔融淬火制造出在可见光和红外区域具有高透明度的新型纳米结构镓锗酸盐基玻璃材料。这些材料可以容纳宽的氧化物组合物，并呈现纳米级相分离，以液滴的形式与锗酸盐基质很好地分离。纳米结构的尺寸可以根据组成来定制。然后，单一热处理允许对应于液滴的唯一玻璃相的选择性结晶。由于晶体生长受到初始相分离尺寸的限制，因此所得玻璃陶瓷材料表现出与母体玻璃中观察到的类似的纳米结构和透明度。各种各样的可获得的组合物与对纳米结构的精确控制相结合，为设计具有广泛可调光学特性的新型高透明纳米结构玻璃和玻璃陶瓷材料提供了绝佳的机会。
New nanostructured gallogermanate‐based glass materials exhibiting high transparency in the visible and infrared regions are fabricated by conventional melt‐quenching. These materials can accommodate wide oxide compositions and present nanoscale phase separation, in the form of droplets well separated from the germanate matrix. The size of the nanostructures can be tailored depending on the composition. A single heat treatment then allows selective crystallization of the sole glassy phase corresponding to the droplets. As the crystal growth is limited by the size of the initial phase separation, the resulting glass‐ceramic materials exhibit nanostructures and transparency similar to the ones observed in the parent glass. The large variety of accessible compositions combined with the precise control over the nanostructure offer a great opportunity to design new highly transparent nanostructured glass and glass‐ceramic materials with a wide range of tuneable optical properties.
