Glass Scintillators (image) Georgia Institute of Technology Share Print E-Mail Caption Pictured here are examples of scintillators produced from molten glass by the researchers. The fluorescence exhibited by the blue scintillators is activated by cerium, while the fluorescence shown by the green scintillator is activated by terbium. The worm-like blue structure is an artifact from the glass-molding process.
