Graphical Abstract

Two rod-shaped Au52(PET)32-G and Au66(PET)38 are synthesized and precisely characterized. Basing on the unreported transverse growth mode from Au52(PET)32-G to Au66(PET)38, six novel nanoclusters are predicted. Although the two nanoclusters have different aspect ratios and near-infrared (NIR) light collection abilities, they have concomitant photothermy (PT) and photoluminescence (PL) under NIR irradiation, and the PT and PL are in balance.

Abstract

Gold nanoclusters exhibiting concomitant photothermy (PT) and photoluminescence (PL) under near-infrared (NIR) light irradiation are rarely reported, and some fundamental issues remain unresolved for such materials. Herein, we concurrently synthesized two novel rod-shaped Au nanoclusters, Au52(PET)32 and Au66(PET)38 (PET = 2-phenylethanethiolate), and precisely revealed that their kernels were 4 × 4 × 6 and 5 × 4 × 6 face-centered cubic (fcc) structures, respectively, based on the numbers of Au layers in the [100], [010], and [001] directions. Following the structural growth mode from Au52(PET)32 to Au66(PET)38, we predicted six more novel nanoclusters. The concurrent synthesis provides rational comparison of the two nanoclusters on the stability, absorption, emission and photothermy, and reveals the aspect ratio-related properties. An interesting finding is that the two nanoclusters exhibit concomitant PT and PL under 785 nm light irradiation, and the PT and PL are in balance, which was explained by the qualitative evaluation of the radiative and non-radiative rates. The ligand effects on PT and PL were also investigated.
