Fig. 4From: Facile Bottom-up Preparation of WS2-Based Water-Soluble Quantum Dots as Luminescent Probes for Hydrogen Peroxide and GlucoseUV–Vis absorption spectra of WS2 QDs (blue line) and CD/WS2 QDs (orange dot line). UV–Vis spectra of WS2 QDs and CD/WS2 QDs in the presence of H2O2 are plotted as green dashed line and red dashed line, respectively. The brown dashed dot line shows the absorbance for H2O2 alone.
