2D Orthogonal Composition‐Gradient Perovskite Photodetection Chip for Computational Spectrometry and Imaging
Miniaturized computational spectrometers are highly desired for intelligent sensing and imaging, which require both a high‐spatial‐resolution photodetector array in hardware and an accurate spectral reconstruction algorithm in software. Herein, we design a space‐confined anion exchange strategy to construct continuou...
