具有强X射线辐射发光的有机-无机杂化团簇在闪烁体领域中表现出巨大的潜力. 然而, 在不牺牲团簇闪烁性能的情况下制备X射线成像屏是具有挑战性的. 报道了一种通过真空蒸发沉积的方法来制备两个合成Cu(I)团簇的高质量闪烁膜. 所制备的具有刚性分子结构的Cu(I)团簇表现出优异的闪烁性能, 光产额高达19356.7光子/MeV, 检测限低至158 nGy/s. 基于真空蒸发沉积制备的Cu(I)团簇闪烁薄膜十分均匀, 表面粗糙度值很小, 仅为1.04 nm, 可应用于各种物体的X射线成像. 这些结果不仅为开发高性能有机-无机杂化闪烁体提供了重要指导, 而且为用于高质量X射线成像应用的非掺杂闪烁屏制备铺平了道路.

Organic-inorganic hybrid clusters with strong X-ray radioluminescence have exhibited great potential in scintillator field. However, fabricating the X-ray imaging screens of the clusters without sacrificing the scintillation performance is challenging. Herein, we report an effective way to prepare high-quality scintillation films of two synthesized Cu(I) clusters through vacuum evaporation deposition. The developed Cu(I) clusters with rigid molecular structures show excellent scintillation performance with a high light yield of up to 19356.7 photons/MeV and a low detection limit of 158 nGy/s. The scintillation film based on the Cu(I) clusters made by vacuum evaporation deposition is highly uniform with a small surface roughness value of 1.04 nm, which can be applied to X-ray imaging for various objects. These results not only provide important guidance to develop high-performance organic-inorganic hybrid scintillators, but also pave a straightforward way to prepare non-doped scintillation screens for remarkable X-ray imaging applications.
