Suspensions of HgTe colloidal quantum dots (CQD) are readily synthesized with infrared energy gaps between 3 and 12 microns. Infrared photodetection using dried films of these CQDs has been demonstrated up to a cutoff wavelength of 12 microns. The synthesis of CQDs and the fabrication of detector devices employ bench-top chemistry techniques, leading to the potential for the easy manufacture of infrared photon detecting imagers at low cost. Recent electrical and optical measurements of these CQD films are discussed. Recent successful prototypes of complete focal plane arrays from CQD films and commercially-available ROICs are also described.
