We developed red-emitting Eu-doped TAGG (Tb3AlxGa5-xO12) nanoparticle scintillators with different compositions. The nanoparticles were synthesized via the sol-gel method. Upon X-ray irradiation, all the samples exhibited red emission. The highest photoluminescence quantum yield was over 70% for x=0.
