Wide Spectral Response Nanocrystal-Sensitized Focal Plane Array

ABSTRACT: The printed nanocrystal detector technology will enable low cost, wide-spectral-response imagers. Phase I will use high volume synthesis methods where nanocrystal films will be fabricated and characterized. Solution processing allows nanocrystal films to be deposited or printed directly onto ROICs, so that high resolution (e.g.<10 m pitch) focal planes can be made at low cost, without the need for indium bump bonding. To demonstrate this capability, candidate visible, NIR, SWIR, and MWIR nanocrystal films will be printed directly onto large format, small pixel pitch readout integrated circuits (ROICs) and their performance demonstrated and characterized. In Phase II, fully-functional, wide spectral response, focal plane arrays will be fabricated and their performance characterized in field tests. BENEFIT: Applications include ground/air mission applications that require day/night imaging of scenes, active/passive imagers using continuous wave/pulsed sources in spectral bandwidths encompassing visible spectrum through long-wave IR, as well as aides for first-responder and search-and-rescue.
