摘要
We apply spectral ellipsometry (SE) to analyze the in-depth morphology of a polymer/fullerene film. Observed fullerene concentration gradients within the film are investigated with respect to temporal changes. The changes within the fractional composition of the polymer/fullerene film are resolved and can be correlated to the formation of fullerene segregations near the surface. (C) 2011 Elsevier B.V.
