A Single-Dot Perovskite SpectrometerLinqi Guo, Haoxuan Sun,* Min Wang, Meng Wang, Liangliang Min, Fengren Cao, Wei Tian, and Liang Li*There are significant applications for miniature on-chip spectrometers in many fields. However, at present, on-chip spectrometers have to utilize an integrated strategy to achieve spectral analysis, which undoubtedly squanders the photosensitive area and adds pressure to the miniaturization of the spectrometer. Here, a unique spectrometer design that adopts a sing
