Description

The Navy is seeking a novel quantum colloidal dot nanocrystal-based photodetector with improved photoluminescence quantum yield (PLQY) at 5 µm for mid-wave infrared (MWIR) imaging. The goal is to develop a cost-reducing architecture by depositing light-sensitive colloidal quantum dot films directly onto Si/SiO2-based ROICs, eliminating complex bonding processes. The technology should enable pixel sizes of 20 µm or less and demonstrate scalability and compatibility with electrical readout. The effort includes developing new materials and processes, fabricating and testing small-scale detector structures, and improving manufacturing quality through iterative build-test cycles.
