摘要
We have used seen different techniques to measure the anisotropic refractive index of poly(vinylcarbazole) films. These techniques are: two types of variable angle spectroscopic eillipsometry (VASE) with multiple sample analysis, Interference enhanced VASE, Transmittance combined with VASE, Polarised Reflectance, beta-scan VASE, and prism coupling. We have found the average ordinary and extraordinary indices at 633 nm to be n(o) = n(TE) = 1.675 +/- 0.008, and n(e) = n(TM) = 1.722 +/- 0.018; respectively, consistent amongst methods and conclusive on the magnitude of Delta n in polymer films. Average refractive indices for PVK from three techniques.
