dc.description.abstractGraphitic carbon nitride (gCN) quantum dots, in recent years, have captivated immense interest in the field of sensing due to their unique optical and electronic properties. Here, we present a facile synthesis of silver nanoparticles embedded sulfur doped gCN quantum dots (Ag-S-gCN QDs) from thiourea, trisodium citrate, and silver nitrate by a low-temperature thermal treatment. The synthesized Ag-S-gCN QDs, with an average size of 3.7 nm, emitted strong blue fluorescence with a high relative quantum yield of 36.5 %. They exhibited significant stability against photobleaching and high ionic strength. The aforementioned quantum dots, under optimal conditions, were employed for fast, sensitive, and selective sensing of Hg2+ ions in distilled water as well as real water samples. A static quenching mechanism was established from the average lifetime calculation via a time-resolved decay experiment. The presence of silver nanoparticles resulted in a redox reaction with Hg2+ ions via electron transfer from metallic Ag to Hg2+ ions. Moreover, the proposed sensor was anticipated to open up a new avenue for convenient, sensitive, and selective sensing of potentially hazardous Hg2+ ions with substantial results.en_US
