In article number 1900079, Shumin Xiao, Qinghai Song, and co‐workers demonstrate a perovskite metasurface at the working wavelength of 632 nm, displaying high‐efficiency polarization conversion, anomalous reflection, and meta‐holograms. The bandgap of the perovskite can be post‐synthetically and reversibly tuned via anion exchange. For the holograms, reflected light is imaged on a screen, where the experimental results of “ON” and “OFF” are displayed simultaneously. The designed devices should have future applications in the semiconductor field.
