Time-resolved radioluminescence (TRRL) properties of the Cu(I) cluster Cu 4 I 6 2- upon pulsed X-ray, β-ray or α-particle excitation are described. The longer (>2 μs) TRRL component displays exponential decay comparable to pulsed UV excitation; however, temporal behaviour at shorter times indicates that high local excited state density provides an alternative decay channel.
