An Ultraviolet-to-NIR Broad Spectral Nanocomposite Photodetector with Gain

Optical sensing from the ultraviolet (UV) to the near infrared (NIR) range have broad applications including imaging, telecommunications,biomedicine, environmental monitoring and defence sensing. [ 1–3 ] It is desirable to have a photodetector with a response spectrum covering a broad spectral range from UV to NIR. However, commercially available solid-state photodetectors have relatively nar…
