Abstract

Photoluminescent gold nanodots (Au NDs) on aluminum oxide nanoparticles (Al₂O₃ NPs) with the emission wavelengths ranging from 510 to 630 nm are unveiled. Orange Al₂O₃ NP@AuNDs show high selectivity and sensitivity towards Ag⁺ ions by metallophilic Ag ⁺-Au⁺ interactions and induced fluorescence quenching of Au NDs.
