摘要

Optical structural texture, also known as structural color, serves as a physically-based color presentation method that aligns with the current societal focus on sustainable development and environmental protection due to its environmental friendly and safe advantages. Through the rational design of grating structures, various visual effects such as dynamic and three-dimensional images can be achieved on packaging, thereby enhancing the product's added value and brand image. This has led to its widely used in the packaging and printing industry. In this paper, we propose a plasmon-driven light-induced generation of optical structural textures that boasts higher resolution, finer stripes, and more flexible design expressions. By changing the angle between two coherent light beams, the period of the resulting grating can be flexibly altered, allowing for the fabrication of grating structures with different periods. During the experiment, angles θ of 5°, 24.85°, and 88.4° were utilized, yielding the grating periods of 5.596 μm, 1.134 μm, and 350 nm, respectively. Furthermore, this method offers advantages in terms of environmental friendly, simple operation, high efficiency, and low cost.
