Evaluation of Polyvinylalcohol:Rhodamine Film Deposition Using Optical Waveguide and Surface Plasmon Resonance Spectroscopies

Evaluation of Layer-by-layer Thin Film of PDADMAC:Alcian Blue and PSS Using Surface Plasmon Resonance and Optical Waveguide Spectroscopies

“…However, it is difficult to estimate the film thickness by the OWG spectroscopy only. Previously [3], we proposed an OWG sensor with surface plasmon resonance (SPR) technique [4,5]. The sensor allows us to obtain the optical absorption and thickness of a thin film simultaneously.…”
