Abstract:
Structural colors arise from selective light interaction with (nano)structures, which give them advantages over pigmented colors such as resistance to fading and possibility to be fabricated out of traditional low-cost and non-toxic materials. Since the color arises from the photonic (nano)structures, different structural features can impact their photonic response and thus, their color. Therefore, the detailed characterization of their structural features is crucial for further improvement of structural colors. In this work, we present a detailed multi-scale structural characterization of ceramic-based photonic glasses by using a combination of high-resolution ptychographic X-ray computed tomography and small angle X-ray scattering. Our results uncover the structure-processing-properties\' relationships of such nanoparticles-based photonic glasses and point out to the need of a review of the structural features used in simulation models concomitantly with the need for further investigations by experimentalists, where we point out exactly which structural features need to be improved.
摘要:
结构颜色来自与(纳米)结构的选择性光相互作用,这使它们比着色的颜色具有优势,例如抗褪色性以及用传统的低成本和无毒材料制造的可能性。由于颜色来自光子(纳米)结构,不同的结构特征会影响它们的光子响应,因此,他们的颜色。因此,详细表征其结构特征对于进一步改善结构颜色至关重要。在这项工作中,我们通过结合使用高分辨率重叠X射线计算机断层扫描和小角度X射线散射,对陶瓷基光子玻璃进行了详细的多尺度结构表征。我们的结果揭示了这种基于纳米粒子的光子玻璃的结构-处理-性质关系,并指出需要对模拟模型中使用的结构特征进行审查,同时需要实验者进行进一步研究。在这里我们准确地指出哪些结构特征需要改进。
