US Patent 9941433 Composite quantum-dot materials for photonic detectors

A composite quantum-dot photodetector comprising a substrate with a colloidally deposited thin film structure forming a photosensitive region, the thin film containing at least one type of a nanocrystal quantum-dot, whereby the nanocrystal quantum dots are spaced by ligands to form a lattice, and the lattice of the quantum dots has an infill material that forms an inorganic matrix that isolates the nanocrystal quantum dots from atmospheric exposure.
