摘要：

Our aim is to improve the charge-generation efficiency of organic-photorecepror materials used in xerography and for laser printers by mixing the material with buckminsterfullerene C-60. The improvement is based on an electron transfer from the excited excitonic state of the photoreceptor molecule to the C-60 thus reducing the recombination probability. Typical materials studied are various metal-phthalocyanines (M-Pc, with M=TiO, VO, Ni, Fe, Cu) and metal-free H-2-Pc. Using techniques like X-ray absorption near edge spectroscopy (XANES) and photoelectron spectroscopy with ultraviolet radiation (UPS) we demonstrate that the electron transfer is energetically possible and no ground state electron transfer occurs. The observation of fluorescence quenching upon doping with C-60 validates the electron transfer-model. (C) 1999 Elsevier Science Ltd. All rights reserved.
