Abstract

We report here a series of original ligand-supported trigonal planar Au@Ag₃ clusters exhibiting bright solid-state phosphorescence in violet to deep-blue range (λ_max =410-442 nm) with remarkably short decay times (0.36-1.36 μs) and up to 96 % emission quantum yield at 298 K.

Keywords: clusters; metal-metal interactions; phosphine ligands; phosphorescence; photophysics.
