DECAY TIME OF LIGHT-EMISSION FROM CERIUM-DOPED SCINTILLATING GLASS
1989
Abstract The cerium-doped scintillating glass GS1 has previously been reported to have a fast emission decay time of about 50 ns. Here measurements are reported which show that the decay is much slower and has a very long tail up to 1 ms. A fit to the decay time distribution requires many components, indicating that the emission of light is a complex process. Varying the percentage of cerium content and annealing temperature of the glass did not change the time characteristics. These results mean that GS1 glass is unsuitable for high rate counting experiments.
