However, research on their semiconductor characteristics, especially the photoluminescence performance, is still in a preliminary stage and the experimental verification is scarcely reported, significantly restricting their further applications. Herein, the photoluminescence property of AMQDs is experimentally verified. The AMQDs are prepared by probe sonication\u2010assisted liquid\u2010phase exfoliation and show robust blue fluorescence, and the photoluminescence is hardly affected by pH. In view of the derivatization reaction of tetracyclines (TET) at different pHs, AMQDs are developed as a pH\u2010mediated dual\u2010channel ratiometric fluorescent probe for TET detection. Under acidic conditions, the AMQDs\u2019 probe exhibits unique recognition behavior due to the inherent fluorescence of TET and the solvent\u2010enhancing effect, that is, the fluorescence changes from blue to red. Under alkaline conditions, this fluorescent probe realizes the transition from blue to yellow\u2010green because of the decomposition of TET. The limits of detection are 27 <jats:bold>\u00d7<\/jats:bold> 10<jats:sup>\u22129<\/jats:sup> and 74 <jats:bold>\u00d7<\/jats:bold> 10<jats:sup>\u22129<\/jats:sup> <jats:sc>m<\/jats:sc>, respectively. The high sensitivity and remarkable fluorescence changes make AMQDs ideal probes for TET sensing. Additionally, this is the first report on the photoluminescence property of AMQDs. It is believed that this work will open a new avenue for AMQDs in optical sensing
