Infrared (IR) detection approaches have required significant development of highly sensitive arrays for a wide range of area. How to engineer materials to achieve high IR sensitivity and be deposited onto lenses, goggles, or other substrates are challenging and important to military and commercial applications. For many military missions, a cost-effective, ultra-compact, and efficient infrared detection is desired. High efficiency upconverting films have the potential to generate visible emissions for direct IR detection. We have successfully shown in Phase I that our nanostructured upconverting glass ceramic films were capable of meeting the needs of direct detection of multiple IR wavelengths at low costs. Efforts to further increase the up-conversion efficiency and to implement additional wavelength detection ranges will be conducted during Phase II. BATi is confident that the encouraging results achieved in Phase I will turn into a great commercial success in the next stage.
