Abstract
Spectrally selective, narrowband light detection is vital for full-color and Near Infrared (NIR) imaging, intelligent monitoring and machine vision. This is not possible using traditional broadband absorbing inorganic semiconductors without input filtering, nor narrowband absorbing organic semicondu...
