AFM and FE-SEM surface morphologies, UV-Vis spectra and NH3 gas sensing characteristic of the composite films were studied. The results showed that the PEDOT:PSS+nc-TiO2 film with a content of 7.0 wt.% of TiO2 is suitable for both the hole transport layer and the NH3 sensing characteristic. The response time of the sensor made from this composite film reached a value as fast as 30 s. The rapid response to NH3 gas could be attributed to the efficient movement of holes as the major charge carriers in the PEDOT:PSS+nc-TiO2 composite films. Useful applications in the organic electronic devices like light emitting diodes and gas thin film sensors can be envisaged. publisher: Vietnam National University Hanoi date: 2017-08 type: Article type: PeerReviewed format: application/pdf language: en identifier: https://eprints.uet.vnu.edu.vn/eprints/id/eprint/2859/1/03-NNDinh-LM%20Long%20et%20al-HPU2%20J-Sci-2017.pdf identifier: Nguyen, Nang Dinh and Lam, Minh Long (2017) CONJUGATE POLYMER PEDOT:PSS INCORPORATED WITH NANO-PARTICLES USED FOR GAS SENSIN.
