Organic device is degraded by oxidation and moisture, but the antioxidant effect of the carotenoid-based dye extracted from spinach has been found to improve the life time of the device. In this research, we report to evaluate the time variation of PL spectrum of MDMO-PPV with β-carotene isolated and purified from spinach by column chromatography.
