- •
CdSeTe/ZnSe/ZnS quantum dots were synthesized for the first time.
- •
A novel soluble quantum dot–graphene oxide (QD–GO) nanocomposite was prepared.
- •
Four ubiquitous PAHs were tested for their affinity to the novel QD–GO probe.
- •
The LOD for phenanthrene in water was 0.19 µg/L.
- •
Detection may be based on an adsorption-fluorescence enhancement effect.
