Abstract : The primary objective of the grant was to investigate a thermal sensing technology and associated materials that extract thermal profiles from explosions in agent defeat test using micro- and nanoparticle trap luminescence. The number of occupied traps in a ceramic varies dynamically with temperature. Therefore, if the traps in a microparticle are filled prior to an agent defeat test using deep UV light or ionizing radiation, then the trap luminescence afterwards is a probe of the thermal history of the test.
