The photo-electronic transfer across membrane between C60 and CdS nanoparticles

The photoelectric property of the composite assembly of C60 and CdS nanoparticles fabricated by LB technique was studied. The luminescence of CdS nanoparticles band–band exciton emission was extremely quenched resulted from the photocharge transfer from CdS nanoparticles to C60 across a lipidic layer (about 2–3 nm). The fatty layer between C60 and CdS nanoparticles played an important role in preventing photocharge recombination in their composite assemblies. 2003 Elsevier Science B.V. All rights reserved. The photoelectric properties of semiconductor nanoparticles, C60 and their composite nano-structure have been widely paid attention [1–3]. C60 with superior electron acceptor capability has been used to develop novel photo-electronic ma-terials with the characteristic of photoinduced charge transfer [2,4–13]. High photocurrent was observed in a system consisting of conjugate
