不需要复杂的彩色滤光片和干涉光学器件的直接全色光电探测器已经引起了广泛的应用。然而，结合各种多光谱半导体和提高高性能光电器件的光子传输效率的困难阻碍了这些平台转化为实际实现。在这里，我们报告了在宽波长范围（365至13（10）nm）内的低温（4.2 × 10（17）琼斯）和光响应度（>8.3 × 10（3）A W-1）。在此基础上，在类皮肤软平台上实现了波长可分辨的光电晶体管电路阵列（>600个光电晶体），有望成为宽光谱图像传感器和面向人体的生物器件的通用和可扩展的方法。
Direct full-color photodetectors without sophisticated color filters and interferometric optics have attracted considerable attention for widespread applications. However, difficulties of combining various multispectral semiconductors and improving photon transfer efficiency for high-performance optoelectronic devices have impeded the translation of these platforms into practical realization. Here, we report a low-temperature (4.2 x 10(17) Jones) and photo-responsivity (>8.3 x 10(3) A W-1) in a broad range of wavelengths (365 to 13(10) nm). On the basis of these technologies, a wavelength discriminable phototransistor circuit array (>600 phototransistors) was implemented on a skin-like soft platform, which is expected to be a versatile and scalable approach for wide spectral image sensors and human-oriented biological devices.
