Abstract
Direct detector materials must exhibit several attributes including both good photon absorption properties and high charge collection, as well as low dark current and good uniformity. These are difficult to achieve in a single material. So far no photoconductor material has been found with sufficiently good properties to realize the full potential for high sensitivity, and know detectors are not compatible with large cross sectional areas, or low cost. A new class of large area, direct-detector pixellated radiation sensors, which integrates many of the beneficial features of several of the more promising of contemporary scintillating and direct-detection materials, are needed Solution-processed, large area radiation detectors will be developed and processed using 6 nm diameter nanocrystals (NCs) deposited on microstructured anodes. This approach allows very large area, high pixel density, detectors to be fabricated, with resolution enhanced due to the reduced charge migration path affored by the microstructured anode. Commercial Applications and Other Benefits: New detector technologies are entering the world of medical X-ray imaging. The flexibility and cost advantages of the proposed approach has significant advantages when one considers a majority of the earth
