Branched Alkyl Chains Tunable Organic‐Inorganic Hybrid Manganese Halides for Anti‐counterfeiting, White Light‐emitting Diode and X‐ray Imaging Applications

shows great application potential in the fields of white light-emitting diode (WLED) and express security check due to its outstanding luminescence performance. This work not only offers two kinds of new Mn-based OIMH materials but also authenticates the role of extending the branched alkyl chain for improving the photoluminescence performance.
