Characterization of Poly (9-vinylcarbazole) and 8-Hydroxyquinoline Aluminum Using a Homemade Rotating Analyzer Ellipsometer

Abstract

In this work we use a homemade spectroscopic ellipsometer to study two commonly used organic materials; namely poly (9-vinylcarbazole)(PVK) and 8-hydroxyquinoline aluminum (Alq3). The ellipsometric parameters ψ and Δ are measured as a function of the wavelength. Fresnel's equations are then inverted to obtain the optical parameters and the thickness of these samples. The dispersion of the refractive index of Alq3 and PVK thin films is found to obey Cauchy’s equation.
