Absorption of fullerene-loaded cages, embedded in PMMA matrix. Empty cage absorption spectra (filled regions) are essentially indistinguishable from C60-loaded spectra (solid lines). Additional intensity in the spectra corresponding to C70-loaded cages (dashed lines) below 500 nm may reflect fullerene absorption or scattering.
