Transparent glass‐ceramics, merging the attributes of both glass and ceramics, have diverse applications in ballistic protection, armor materials, dentistry, light‐emitting diode, and optical domains. A limitation of conventional methods for glass‐ceramic fabrication is their inadequacy in precisely controlling the morphology of crystallization, consequently constraining their prospective advancements in diverse areas. Here, a method that facilitates precise control over the formation and growth of polarization‐dependent nonperiodic anisotropic nanocrystals, with a short axis ranging from 15 to 280 nm, in Li2O‐Al2O3‐SiO2 (LAS) glass is proposed. The method utilizes the principles of near‐field anisotropy between light and matter, building upon the classical nucleation‐growth model of glass crystallization. Notably, the glass‐ceramics possessing laser‐induced nanocrystals within the Rayleigh size regime showcase an impressive 99.7% transmittance in the visible and near‐infrared wavelengths. Additionally, the glass‐ceramics with non‐periodic anisotropic nanocrystals macroscopically exhibit form‐birefringence properties, thus enabling transparent optical applications, such as polarization elements, geometric phase elements, and multi‐dimensional optical data storage. This work opens up new avenues for morphological manipulation of nanocrystallization, with potential applications in optics, nanophotonics, functional glass‐ceramics, and high mechanical performance devices.

通过激光各向异性纳米晶化制备先进透明微晶玻璃

透明微晶玻璃融合了玻璃和陶瓷的特性，在防弹、装甲材料、牙科、发光二极管和光学领域有着广泛的应用。传统微晶玻璃制造方法的局限性在于它们无法充分精确控制结晶形态，从而限制了它们在不同领域的前景发展。在这里，一种有助于精确控制 Li 中短轴范围为 15 至 280 nm 的偏振依赖性非周期性各向异性纳米晶体的形成和生长的方法2氧铝2氧3-二氧化硅2建议使用（LAS）玻璃。该方法利用光和物质之间的近场各向异性原理，建立在玻璃结晶的经典成核生长模型的基础上。值得注意的是，具有瑞利尺寸范围内的激光诱导纳米晶体的玻璃陶瓷在可见光和近红外波长下表现出令人印象深刻的 99.7% 透射率。此外，具有非周期性各向异性纳米晶体的玻璃陶瓷在宏观上表现出形式双折射特性，从而实现透明光学应用，例如偏振元件、几何相位元件和多维光学数据存储。这项工作为纳米结晶的形态操控开辟了新途径，在光学、纳米光子学、功能玻璃陶瓷和高机械性能器件中具有潜在的应用前景。
