Near-infrared-emitting tin-based perovskite light-emitting diodes with greatly improved efficiency are realized by the use of additives during fabrication.
A hyperspectral camera based on a random array of CMOS-compatible Fabry–Pérot filters is demonstrated. The hyperspectral camera exhibits performance comparable with that of a typical RGB camera, with 45% sensitivity to visible light, a spatial resolution of 3 px for 3 dB contrast, and a frame rate of 32.3 fps at VGA resolution.
