Cover Story: There is an ongoing quest to find blue-emitting materials with a high quantum yield and narrow emission bandwidth for LED applications. A promising class is Cu(I)-based compounds, where the size and electronic structure of the organic countercation modulates the emission properties of the copper(I)-based anion. Yet, the emission mechanism of these halocuprates(I) is not understood. Here, thin films of a molecular salt containing [Cu2Br4]2− as the blue-emitting anion and tetraethylammonium as the countercation are studied using transient absorption and emission spectroscopy. The emission is identified as phosphorescence from a long-lived (57 μs) triplet state, which is formed from the originally excited singlet state with a time constant of 184 ps. The possible implications of LED applications are discussed. View this paper
