摘要：

A unique heterophase ligand exchange induced etching process was used to transform gold nanoparticles into organic-soluble fluorescent gold clusters which were assigned to Au-8 by optical spectroscopy and MALDI-TOF mass spectrometry. Both the annihilation electrochemiluminescence of fluorescent Au-8 clusters in organic solution and the coreactant electrochemiluminescence of Au-8 cluster film in aqueous solution were studied.
