The formation of Au\u2010NC\u2013CdTe QD nanocomposite has been confirmed by TEM, steady state and time resolved spectroscopy, CD and FTIR studies. A significant signal off (74\u2009% PL quenching at 553\u2005nm) phenomenon of this nanocomposite is observed in presence of 6.56\u00d710<jats:sup>\u22127<\/jats:sup>\u2009<jats:sc>M<\/jats:sc> Hg<jats:sup>2+<\/jats:sup> ion, due to salt\u2010induced aggregation. However, a dramatic PL enhancement (128\u2009%) of the Au\u2010NC\u2013CdTe QD nanocomposite is observed in presence of 8.47\u00d710<jats:sup>\u22127<\/jats:sup>\u2009<jats:sc>M<\/jats:sc> F<jats:sup>\u2212<\/jats:sup> anion. The calculated limit of detections (LOD) of Hg<jats:sup>2+<\/jats:sup> ion concentration and F<jats:sup>\u2212<\/jats:sup> ion concentration are found to be 9 and 117\u2005n<jats:sc>M<\/jats:sc>, respectively, which are within the safety range set by the United States Environment Protection Agency. Thus, the simple Au\u2010NC\u2013CdTe QD optical\u2010based sensor is very useful to detect both toxic cations and anions.<\/jats:p>","DOI":"10.1002\/chem.201203576","type":"journal-article","created":{"date-parts":[[2013,3,13]],"date-time":"2013-03-13T15:51:25Z","timestamp":1363189885000},"page":"5980-5987","source":"Crossref","is-referenced-by-count":96,"title":["Detection of Hg<sup>2+<\/sup> and F<sup>\u2212<\/sup> Ions by Using Fluorescence Switching of Quantum Dots in an Au\u2010Cluster\u2013CdTe QD Nanocomposite"],"prefix":"10.1002","volume":"19","author":[{"given":"Bipattaran","family":"Paramanik","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Santanu","family":"Bhattacharyya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amitava","family":"Patra","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2013,3,11]]},"reference":[{"key":"e_1_2_6_1_2","doi-asserted-by":"publisher","DOI":"10.1080\/10937400306474"},{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.med.55.091902.103653"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.aquatox.2004.11.015"},{"key":"e_1_2_6_4_2","doi-asserted-by":"crossref","first-page":"113","DOI":"10.1016\/S0031-6997(24)01438-8","volume":"52","author":"Zalups R.
