摘要

我们报告了在银、金、铜和铝表面的全彩色调色板的独立角度创作。通过使用多脉冲皮秒脉冲，我们展示了高达69%的显着色彩饱和度和高达60%的亮度范围增加。时域有限差分(FDTD)仿真结果表明，高空间频率的LIPSS (HSFL)是改进的主要原因。此外，我们还展示了原子层沉积的氧化铝厚度对颜色的钝化和调谐。

Coloring and color enhancement on noble metals rendered by plasmonic effects via multi-burst picosecond pulses

We report the angle-independent creation of full color palettes on the surface of silver, gold, copper and aluminum. We show significant color saturation of up to ∼69% and an increase in the lightness range by up to ∼ 60% with the use of multi-burst picosecond pulses. Finite-difference time-domain (FDTD) simulations show that high-spatial frequency LIPSS (HSFL) are responsible for the improvements. In addition, we show the passivation and tuning of the colors with the thickness of alumina deposited by atomic layer deposition.
