The first luminescence radical cluster was constructed with open-shell luminescent radical ligands. The spin-allowed doublet emission endows it with 100% exciton utilization and a short radiation decay lifetime on the nanosecond scale, making it suitable for high-resolution X-ray imaging without residual images.
Abstract
Metal clusters, an emerging class of scintillator materials, have attracted much attention owing to their inherently high X-ray absorption, mild synthesis conditions, low toxicity, strong luminescence, and large Stokes shift. However, the decay lifetime of metal clusters is usually on the order of microseconds, which is unfavorable for safety inspection, nondestructive testing, and medical imaging. Here, the open-shell luminescent radical ligand was used to construct the first radical cluster scintillator Cu2I2(L)4. The spin-allowed doublet emission of Cu2I2(L)4 theoretically enabled 100% exciton utilization and exhibited a short radiation decay lifetime on the nanosecond scale. Cu2I2(L)4 can be fabricated into a flexible scintillator screen for X-ray imaging, achieving a high resolution of 30.7 LP mm−1. More importantly, the Cu2I2(L)4 scintillator screen has no residual images during X-ray imaging. This work reports the first luminescent metal cluster with a radical ligand and presents a new strategy for constructing short lifetime X-ray scintillators.
