Spectroscopic detection of gamma photons has widespread applications for particle physics research, threat detection and medical diagnosis. We report the development of plastic 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, light yield and radiation hardness will be discussed.
