Time-resolved radioluminescence of the Cu(i) cluster Cu4I62−. Different responses to photo, X-ray, β-ray and α-particle excitation

Time-resolved radioluminescence (TRRL) properties of the Cu(i) cluster Cu4I62− 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 t...

Description
Summary:Time-resolved radioluminescence (TRRL) properties of the Cu(i) cluster Cu4I62− 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.
