英文摘要	A novel route has been developed for surfactant-free synthesis of highly fluorescent gold quantum dots (gqds) in n,n-dimethylformamide (dmf). the as-prepared gqds show instinctive fluorescence and good solubility in water. the formation mechanism and functionalization of gqds were investigated by uv-vis spectra, fluorescence excitation and emission spectra, mass spectra, and tem observation. ligand-dependent optical properties of functionalized gqds were found to be dramatically different. the approach provides a facile method of functionalization of bare gqds for further applications, such as fluorescent biolabels, energy transfer units, and light-emitting devices.
