Abstract : Purified D2O ice was irradiated with pulses of 0.53 MeV electrons and the spectral distributions of the luminescence intensity and half-life were recorded between 200 and 800 nm. Emission peaks were observed at 390 and 540 nm and it was shown that none of these emissions was caused by luminescent impurities. The emission from D2O ice was more intense than from H2O ice at all wavelengths above 370 nm. The half-lives of the luminescence decay in D2O ice varied from 170 ns at 390 nm to 60 ns at 540 nm and were longer than the corresponding values of ca. 140 ns and 25 ns for H2O ice.
