Abstract The photo-stability of both MDMO-PPV film and MEH-PPV film, as irradiated under different conditions, and in the presence and absence of oxygen and visible light luminance, were studied by UV-Vis spectra and fluorescence spectra respectively. The maximum absorbance of them was at 500 nm, while the maximum fluorescence intensity of them were at 580 and 589 nm, respectively. In the presence of both oxygen and light irradiation, the fluorescence intensity was decreased and the films were damaged. Photocatalysis oxidation technology using solid-state nanocrystalline TiO2-PVC film was introduced to increase the photo-stability and some meaningful clues were observed.
