 abstract={Tris(8-hydroxyquinoline)aluminium with poly(N-vinylcarbazole) (Alq 3:PVK) or polystyrene sulfonate (Alq 3:PSS) were deposited by spin-coating on glass and silicon substrates. SEM measurements show that relatively smooth thin films were obtained. Fourier transform infrared measurements were performed to confirm the composition of the samples. The optical properties of thin films containing Alq 3:PVK and Alq 3:PSS were characterised using absorption spectroscopy and spectroscopic ellipsometry. It was found that the absorption spectrum of Alq 3:PVK is characterised by four bands, while for Alq 3:PSS only three bands are visible. The photoluminescence of the studied thin layers shows a peak with a maximum at about 500 nm. Additionally, cyclic voltammetry of Alq 3 is also presented. Theoretical density functional theory calculations provide the insight into the interaction and nature of Alq 3:PVK and Alq 3:PSS excited states. Finally, the organic light-emitting diode (OLED) structure based on Alq 3:PVK was fabricated and showed strong electro-luminescence with a green emission at 520 nm. The results of the device show that the ITO/PEDOT:PSS/Alq 3:PVK/Ca/Al system can be useful for the production of low-cost OLEDs with Alq 3:PVK as an active layer for future lighting applications.},
