英文摘要	Photoresponsive organic field. effect transistors (PhotOFET) require materials with high mobility, high absorbance and high exciton dissociation efficiency. Although great efforts have been made to realize high performance PhotOFET using various organic small molecules and polymeric semiconductors, both the responsivity and mobility were still low based on pristine materials. In this work, gold nanoparticles(Au NPs) were incorporated into the semiconductor layer of OFET. Owing to the surface plasmon effect of the Au NPs, the absorbance of the semiconductor could be greatly increased and high. performance PhotOFET were realized. Au NPs were prepared in situ on the substrates and used to fabricate PhotOFET directly. By utilizing the surface plasmon resonance effect of the Au NPs, high performance PhotOFET with a mobility of 0.12 cm(2) . V-1 . s(-1) and a responsivity of 11.6 A/W was obtained based on the materials without photoresponse in the visible spectrum. The surface chemical modification of gold nanoparticles with alkane thiol played a key role in improving the device performance. The device structure proposed here, i.e. the incorporation of Au NPs into the semiconductor layer of OFETs, provided an effective method for the construction of high performance PhotOFET based on common organic semiconductors.
