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.
