Abstract
A photonic sensor includes a first electrode layer, a second electrode layer, a third electrode layer, a first photon absorption layer, a second photon absorption layer, a third photon absorption layer and a charge blocking layer. The first photon absorption layer includes a dispersion of first nanoparticles, and is configured to transduce a first colored light into corresponding electric charge. The second photon absorption layer includes a dispersion of second nanoparticles, and is configured to transduce a second colored light into corresponding electric charge according to light intensity. The third photon absorption layer includes a dispersion of third nanoparticles, and is configured to transduce a third colored light into corresponding electric charge according to light intensity. The charge blocking layer is formed between the first and second photon absorption layers to block flow of electric charge between the first and second photon absorption layers.
