Film elektrokromik mempunyai spektrum transmisi yang dapat berubah secara reversibel apabila diberi tegangan listrik. Perubahan ini mengganti keadaan tidak tembus cahaya (opaque) ke keadaan bening (transparent) atau sebaliknya, sehingga film dapat digunakan untuk mengatur pancaran cahaya. Dalam makalah ini dilaporkan studi tentang film polianilin sebagai salah satu bahan aktif elektrokromik. Dalam keadaan reduksi, warna film kuning transparan dan dalam keadaan oksidasi hijau sampai biru. Divais elektrokromik yang dibuat terdiri atas lapisan kaca konduktif − film ...

ABSTRACT
Tungsten oxide, has many interesting optical, electrical, structural, and chemical
properties, are an ideal choice material for electrochromic smart windows devices. In
this study, tungsten oxide thin films were prepared by the thermal oxidization on
Tungsten/ITO/glass substrates at different heat-treatment temperatures. The optimum
heat-treatment temperature, corresponding to the maximum electrochromic
performance, was achieved by 550 oC. X-ray diffraction (XRD) analysis indicates that
a tetragonal WO3 phase formed at temperatures below 550 oC and the phase
transformed to monoclinic W18O49 after the temperature ...

This research focuses on developing a characterization method to observe changes in the optical properties of metal oxide materials, particularly BiVO4, during real-time electrochemical processes. This spectroelectrochemical method combines absorbance measurements of the material using UV-vis spectroscopy with electrochemical measurements using cyclic voltammetry simultaneously. The study successfully identified changes in the optical properties of BiVO4 within the potential sweep range of -0.4 VRHE to 2.1 VRHE, due to the electrochromic properties of vanadium in BiVO4. ...
