Abstract
MXene quantum dots (MQDs) derived from MXene with photoluminescent properties have attracted considerable attention. Herein, nitrogen-doped MQDs (N-MQDs) were constructed by a solvothermal method using Ti3C2 MXene as precursors and o-phenylenediamine (oPD) as the nitrogen source. The morphology, element composition and optical properties of N-MQDs were investigated by transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS) and spectroscopy etc. The obtained N-MQDs are dispersed quasi-spherical nanoparticles, mainly composed of carbon, oxygen and nitrogen, with yellow fluorescence at 580 nm and quantum yield of 5.42 %. In further, N-MQDs can detect Alizarin Red (ARS) based on inner filter effect (IFE) with linear range and detection limit of 0–80 μM and 1.21 μM, respectively. N-MQDs can detect ARS in real water samples, and were expected to have further applications in the fields of environmental monitoring and biosensing.
