Nitrogen-doped SiQDs and their PVA fluorescent films for rapid fluorescence detection of chlorogenic acid in green coffee beans.
Nitrogen-doped silicon quantum dots (N-SiQDs) were prepared via a one-pot hydrothermal route, and subsequently utilized to establish a fluorescent sensing system for the rapid determination of chlorogenic acid (CGA). Mechanistic studies revealed a mixed quenching mechanism. The inner filter effect arises from the stron...
