Abstract :
We describe the luminescence and scintillation of indium disilicate (In2Si2O7), an inorganic scintillator containing a large amount of 115In. The maximum fluorescence occurs in the near UV range at 335 nm with a complicated decay including a fast component of less than 100 ns and a long one of more than a microsecond. Room temperature emission intensity was quite weak while the quantum efficiency became reasonably good at cryogenic temperature. Scintillation was measured using α-particles of 6.09 MeV and 8.785 MeV from 300 to 4 K. A maximum of intensity is observed at 50 K. A fast component (τ ⋍ 20 ns) with a constant intensity superimposes to a slow one of which the intensity has a maximum at 50 K and for which the decay constant rises as the temperature decreases.
