a Emission spectra of the p-Phthalic acid with series of different amount of F-MoS₂-FePt NCs and constant concentration of H₂O₂. The reaction conditions are shown as follows: 5 mM TA, 0.25 M H₂O₂, along with different amount of F-MoS₂-FePt NCs. b The corresponding fluorescence intensity of different amount of F-MoS₂-FePt NCs
