可持续光学用二维功能矿物
Two-dimensional Functional Minerals for Sustainable Optics
摘要：
光学器件是我们生活中的重要组成部分，有机液晶目前被广泛用于减少人类印记。然而，该技术仍然存在相对较高的成本、毒性和其他环境影响，不能完全满足未来可持续社会的需求。在这里，我们描述了一种替代的方法，颜色可调的光学器件，这是基于可持续的无机液晶从二维矿物材料在自然界中丰富。蛭石的原型二维矿物是通过绿色方法大规模生产的，具有>103的尺寸-厚度比，>10 emu g-1的面内磁化强度，和>3 eV的光学带隙。这些特性使得二维蛭石具有比有机材料大几个数量级的灵敏磁双折射响应和宽光谱调制能力。因此，我们的发现允许制造各种低能耗甚至零能耗的变色器件，这些器件可用于可持续光学。
英文摘要：
Optical device is a key component in our lives and organic liquid crystals are nowadays widely used to reduce human imprint. However, this technology still suffers from relatively high costs, toxicity and other environmental impacts, and cannot fully meet the demand of future sustainable society. Here we describe an alternative approach to colour-tuneable optical devices, which is based on sustainable inorganic liquid crystals derived from two-dimensional mineral materials abundant in nature. The prototypical two-dimensional mineral of vermiculite is massively produced by a green method, possessing size-to-thickness ratios of >103, in-plane magnetisation of >10 emu g-1, and an optical bandgap of >3 eV. These characteristics endow two-dimensional vermiculite with sensitive magneto-birefringence response, which is several orders of magnitude larger than organic counterparts, as well as capability of broad-spectrum modulation. Our finding consequently permits the fabrication of various chromic devices with low or even zero-energy consumption, which can be used for sustainable optics.
