Abstract

Physical Sciences, Inc. (PSI) has developed an environmentally friendly, microencapsulated chemiluminescent formulation that emits at a tunable visible (deterrent use) or near infrared (covert tag) wavelength, depending upon the fluorophore selected. The chemiluminescence occurs when the microcapsule is ruptured by an intruder or other applied force, activating the luminescent chemistry. PSI will collaborate with the Wiesner Group at Cornell University and utilize their C-Dot technology to enhance chemiluminescent brightness. The microcapsule can be formulated to provide a tunable rupture pressure and contains both adhesion and low observable components. Using the proposed technology for taggant applications, we expect to be able to see an intruder footprint at 1 km standoff using night vision goggles (NVG) by achieving a brightness of greater than 1 microwatt/cm2. At the end of the Phase I program, we will conduct a field test using the taggant material and NVG sensor. A potential Phase II program would include additional formulation, pilot manufacture and field testing of the taggant microcapsules.
