Liu, Nan Shi, Min-Min Pan, Xiao-Wei Qiu, Wei-Ming Zhu, Jian-Hui He, Hai-Ping Chen, Hong-Zheng Wang, Mang Photoinduced Electron Transfer and Enhancement of Photoconductivity in Silicon Nanoparticles/Perylene Diimide Composites in a Polymer Matrix An inorganic−organic hybrid composite was prepared from a soluble N-dodecyl-N′-phenyl-3,4,9,10-perylenetetracarboxylic diimide (DOPP) and silicon nanoparticles (NPs). The silicon NPs were synthesized by a solution-phase method. Remarkable photoluminescence (PL) quenching was observed in the composite dispersed in a polymethyl methacrylate matrix. On the basis of the analysis of the PL quenching mechanism, it was demonstrated that a photoinduced electron transfer from silicon NPs to DOPP could occur in the composite. The photoconductivity of the composite was studied, and the photosensitivity enhancement of the composite was realized due to the photoinduced electron transfer between silicon NPs and DOPP. silicon NPs;PL quenching mechanism;Photoinduced Electron Transfer;DOPP;polymethyl methacrylate matrix;photoinduced electron transfer 2008-10-09
