Abstract:

In this Phase I program, an infrared-sensitive visibly-clear, optical-grade material, capable of upconverting (UC) infrared (IR) scene information into three visible wavelengths will be developed. Ballistic protection goggle-compatible laminates, easily incorporated into swappable lenses, will be made from visibly-transparent semiconductor nanostructures that are sensitized with infrared upconverting additives. In order to generate a thin film for IR detection, nanostructure surface functionalization will be performed to provide matrix-element compatibility and promote UC efficiency. To optimize detectivity and UC efficiency, in Phase I, we will synthesize the nanocrystals and UC materials. Using an orthogonal design experiment, the detector sensitivity, spectral response, optical clarity, visible-spectrum transmissivity, and fabrication technology of the thin-film IR-sensitive UC applique will be optimized. Working with an industrial glass laminate manufacturer, we will design the materials to be compatible with optical grade polycarbonate lens that can be can be interchanged quickly for increased situational awareness, yet provide best-in-class protection. The applique will have a total weight less than 50 grams and will provide greater than 70% visible transmission, while converting at least three non-visible spectrum bands into different visible spectral wavelengths. In Phase II, these materials and will be demonstrated in a proof-of-concept goggle lens.
