Green Carbon Dots for Metal Sensing

<jats:p>In this work, carbon quantum dots (C-dots) was successfully synthesized by hydrothermal treatment using dried leaves as green precursor for metal sensing. The performance of C-dots when detecting metal ions in water will be evaluated by testing with different types of metal stock solutions. Quenching effect of fluorescence C-dots solution was observed in the presence of different metal ions. C-dots is more selective towards Fe<jats:sup>3+</jats:sup> compared to other metal ions.</jats:p>
