Abstract : Results of basic research towards room-temperature, high-speed, high-efficiency, and high-energy-resolution portable scintillating detectors based on colloidal nanocrystals are reported. Novel scintillating nanocrystals were synthesized for the first time, using colloidal approach. For neutron detection, the nanoparticles contain neutron capture elements, while the host polymers serve a dual role of acting as moderators and scintillators. It is expected that this project, if DTRA chooses to continue funding it, will lead to development of high-performance room-temperature portable detectors of nuclear radiation.
