Zero-dimensional Cu(i)-based organometallic halide with green cluster-centred emission for high resolution X-ray imaging screens

Abstract

In this communication, we report a low-dimensional perovskite-related structure based on Cu(I) organometallic halide with strong green cluster-centred emission and near-unity photoluminescence quantum yield. The 0D [Rb(18-crown-6)]₂Cu₄I₆ was sucessfully applied for X-ray imaging screens which exhibit high spatial resolution of 16.8 lp mm⁻¹ and low detection limit of 458 nGy s⁻¹.
