Laser Fabrication of Multi‐Dimensional Perovskite Patterns with Intelligent Anti‐Counterfeiting Applications (Adv. Sci. 42/2024)

Femtosecond Laser Direct Writing of Perovskites By utilizing femtosecond laser direct writing, various perovskite micro and nanostructures can be engraved. These structures, when viewed from a distance, resemble a city, with internal units composed of 3D, quasi-2D, and 2D perovskite. Combined with AI elements (in the top left corner), this laser writting technology enables intelligent recognition and enhances anti-counterfeiting security.
