Improving the sensitivity of silicon-based CMOS and CCD in the deep-UV is an area of ongoing interest. Lumogen has been used for this purpose for many years but has several known issues including limitations to its use in both vacuum and radiation harsh environments. Quantum Dots (QD) offers a more robust alternative to Lumogen. The fluorescence wavelength of QDs is tunable and can be fabricated to match the peak sensor quantum efficiency. Aerosol jet printing (AJP) is being used for the deposition of QDs on a variety of substrates and on commercially available sensor arrays. While the films deposited onto various substrates have a surface morphology characterized by aggregate formations, the insight obtained will lead to much more uniform layers in the near future. Organic residues common to this process, that compromise the UV performance, have been minimized.
