Key Points

The aim is to understand the structural and scintillation characteristics of Ce-doped Y3ScxAl5−xO12 crystals with varying Sc and Al content.
Systematic investigation of pure and Ce-doped Y3ScxAl5−xO12 crystals
High-resolution Sc-45 and Al-27 NMR spectroscopy
Thermostimulated luminescence and electron paramagnetic resonance studies
Scintillation resonance indicates Sc ions primarily occupy octahedral sites
Sc incorporation leads to strong exciton emission at 320–324 nm, significantly exceeding BGO
Ce doping introduces 5d to 4f emission at 518 nm and accelerates scintillation decay
