Abstract
An imaging device includes an array of photosensors. A film of semiconductor nanoparticles is common to the photosensors of the array. The nanoparticles are configured to be excited by light with wavelengths in a range from 280 to 1500 nanometers. Each photosensor includes a top electrode and a bottom electrode positioned on opposite sides of the film of semiconductor nanoparticles. At least some of the photosensors further include a filter configured to transmit light with wavelengths in a range from 280 to 400 nanometers, and to at least partially filter out light with wavelengths greater than 400 nanometers from reaching the photosensor. A transistor level is electrically coupled to the top and bottom electrodes of the photosensors.
