Abstract

We report the photoluminescence (PL) and cathodoluminescence (CL) properties of face-capped [MoXL] (X = Cl, Br, I; L = organic or inorganic ligands) cluster units. We show that the emission of Mo metal atom clusters depends not only on the nature of X and L ligands bound to the cluster and counter-cations, but also on the excitation source. Seven members of the AMoXL series (A = Cs, (n-CH)N, NH) were selected to evaluate the influence of counter-cations and ligands on de-excitation mechanisms responsible for multicomponent emission of cluster units. This study evaluates the ageing of each member of the series, which is crucial for further energy conversion applications (photovoltaic, lighting, water splitting, etc.).
