Micro/nanostructured perovskites with spatially graded compositions and bandgaps are promising in filter-free, chip-level multispectral and hyperspectral detection. However, achieving high-resolution patterning of perovskites with controlled graded compositions is challenging. Here, we present a programmable mixed electrohydrodynamic printing (M-ePrinting) technique to realize the one-step direct-printing of arbitrary spatially graded perovskite micro/nanopatterns for the first time.
