Measurement of the Anisotropic Refractive Indices of Spin Cast Thin Poly(2-methoxy-5-(2′-ethyl-hexyloxy)-p-phenylenevinylene) (MEH-PPV) Films

Variable angle spectroscopic ellipsometry measurements (see Figure for principle) show that thin spin-cast films of MEH–PPV are highly anisotropic. Accurate dispersion data for the refractive index and the dielectric function of MEH–PPV in the energy range 1.24 to 5.00 eV are also given.
