Study on Femtosecond Laser Induced Structural Colors
In this chapter, we prepared various micro/nanostructures and realized the colorizing the materials surface. By adopting different laser pulse overlaps several kinds of structural colors were produced on the aluminum surfaces. In addition, we not only discussed the combined influence of incident light angle and the ripples orientation on the diversity of structural colors, but also proposed the possibility of producing multi-patterns constituted by ripples with different orientations, and realized the diverse and exclusive display. Furthermore, the preparation of three-dimensional effect patterns on metal surface was proposed.
