•Organic field-effect transistor (OFET) with nanoparticle (NP) film was fabricated•Electrical and optical properties of NP and OFET were studied upon UV irradiation•We report a transition from charge trapping to conduction mechanism of NPs in OFET
Self-assembled monolayers of metal nanoparticles (NPs) are envisioned for various devices and have been investigated for possible applications. However, organic envelope of NPs which is required for self-assembling must be often removed prior further device fabrication. Here, we report on effect of ozonolysis on monolayer of silver NPs (Ag NPs) with size of 8 nm and its impact on Ag NPs utilization in organic field-effect transistor. It was found that Ag NPs covered by organics serve like a traps and removal of insulating organics decreases number of traps and consequently increases Ag NPs monolayer conductivity.
