N‐doped GQD photodetector hybridized with Au nanoparticles. a) UV–vis absorption spectra of N‐GQDs and Au/N‐GQDs. The vertical dashed lines show the absorption peaks corresponding to N‐GQDs (262 nm) and plasmonics Au NPs (547 nm). b) Responsivities of of N‐GQDs and Au/N‐GQDs photodetector under 5 V bias. c) Schematic illustration of the band diagram and the electron transfer in Au/N‐GQDs under light illumination.
