Abstract

Organic thin-film transistors (OTFTs) with reduced-photosensitivity have been made by blending titanium dioxide (TiO2) nanoparticles into the polymer dielectric layer. The minimized shift of threshold voltage and more stable photocurrent are attributed to the introduction of recombination centers induced by the doping of TiO2 nanoparticles. The localized energy levels deep in the energy gap and away from highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) of pentacene may serve as the recombination centers, which can enhance substantially the recombination process in the OTFTs.
