Strong Coupling in all‐Polymer Planar Microcavities

Daniela Di Fonzo, Andrea Lanfranchi, Giovanni Manfredi, M. Patrini et autres

ABSTRACT In this work, strong coupling effect is observed in all‐polymer planar microcavities incorporating TDBC J‐aggregates dispersed into polyvinyl alcohol in the cavity layer. Angle‐resolved polarized‐light transmittance and reflectance spectra clearly reveal the characteristic anti‐crossing between the excitonic transition and the microcavity …

Spectroscopic Ellipsometry of Conducting Anisotropic Pedot thin Films

Francesco Bisio, Katia Sparnacci, Angelo Angelini, Martina Martusciello et autres

We report a comprehensive spectroscopic investigation of poly[3,4-ethylenedioxythiophene] (PEDOT) thin films, including both those synthesized from solution in the doped state and from commercial PEDOT:PSS (poly(styrene sulfonate)) formulations. Variable-angle spectroscopic ellipsometry is combined with transmittance and reflectance measurements spanning the UV to …

Stretchable Distributed Bragg Reflectors as Strain-Responsive Mechanochromic Sensors

Martina Martusciello, Andrea Lanfranchi, Maila Castellano, M. Patrini et autres

Mechanochromic materials exhibit color changes upon external mechanical stimuli, finding wide-ranging applications in colorimetric sensing, display technology, and anticounterfeiting measures. Many of these materials rely on fluorescence properties and therefore necessitate external optical or electrical excitation. However, for broader applicability, the detection …
