From: Metal-enhanced fluorescence and excited state dynamics of carotenoids in thin polymer films
Absorption (black) and emission (red) spectra of 8′-apo-β-caroten-8′-al (carotenal) in (a) PS and (b) PEG film. Solid and dashed red lines represent the fluorescence spectra (λex = 405 nm) of carotenal with and without a SIF, respectively. Emission spectrum of carotenal without a SIF in PEG was augmented by 3 times for comparison.
