Notes:
Fluorescence scanning near-field optical microscopy with a spatial resolution of ∼150 nm is used to investigate blends of conjugated polymers in a poly(methylmethacrylate), PMMA, matrix. These blends, which phase segregate on a length scale of several hundred nanometers, have a high degree of correlation between their fluorescence and topographic images, as illustrated by measurements taken from a sample of 5% by weight of poly(2-methoxy-5-(2′,6′-dimethyloctyloxy)-pphenylenevinylene), "OC1C10" PPV, in PMMA. In a blend containing both poly(2,5-dihexyloxyp-phenylenevinylene), CN-PPV, and poly(2-dimethyloctylsilyl-p-phenylenevinylene), DMOS-PPV, spectroscopic contrast was used to identify material both on the surface and buried within a thin transparent film. © 1999 American Institute of Physics.
