报告摘要：

Spectroscopic detection of ionizing photons has widespread applications for particle physics research, nuclear threat detection and medical diagnosis. We report the development of nanocomposite scintillators for gamma photoelectric generation. High-Z nanoparticles are loaded at high concentrations to enhance the gamma cross-section, and conjugated organic luminescent compounds are investigated to boost the light yield. Factors affecting the synthesis, optical transparency in bulk solids, light yield and radiation hardness will be discussed. The nanocomposites have been further functionalized to simultaneous detect fast and thermal neutrons.
