The efficiency of charge generation in organic photoconducting materials plays a major role in developing new non-toxic and inexpensive compounds for xerographic applications. In this work investigations on C60-doped metal-free phthalocyanine (H2-Pc) are presented. The doping with the fullerenes leads to a remarkable enhancement of the generation of free charges in H 2-Pc under illumination. One goal of this work was to show that this is due to a photoinduced electron-transfer from Phthalocyanine to C 60. Several experimental methods such as optical and photoelectron spectroscopy and photoelectric measurements were used to obtain informations about this process . Photoconductivity measurements showed a increased photogeneration efficiency of the C 60-doped samples. The photoinduced charge-transfer could be observed directly by timeresolved fluorescence and photoemission spectroscopy. Botte the energy and the typical timescale of this process could be determined . Based on the results of the time-resolved spectroscopy measurements, a model for a dopant-assisted charge-carrier generation has been developed. |
