Effect of In-doping on electrochromic behavior of NiO thin films
Materialia, 2023Undoped and Indium doped Nickel Oxide (NiO) thin layers with different doping content (2, 4, 6 at.%) were successfully deposited on glass and Indium-doped Tin Oxide (ITO) substrates using spray pyrolysis (SP) technique. The effect of indium on the microstructural, morphological, optical, and electrochromic behaviors of NiO films was investigated by X ...

Electrochromic effect in Q-carbon
Applied Physics Letters, 2018Here, we report the electrochromic effect in undoped Q-carbon. This unique phase of carbon, Q-carbon, is formed by pulsed laser melting of amorphous carbon and subsequent ultrafast quenching process. The excess amount of unpaired electrons near the Fermi energy level in the Q-carbon causes a 48% increase in the optical absorption at 265 nm with an ...

Neutral state colorless electrochromic polymer networks: Spacer effect on electrochromic performance
Polymer, 2014Abstract A series of carbazole-based monomers and their corresponding polymers with various spacer units were synthesized and coated onto ITO-glass surface via an electrochemical cross-linking process. All carbazole-based polymers exhibited multi-electrochromic behavior thanks to two separate oxidation processes. All materials were characterized by

Effects of Electrochromic Glass on Computer Vision Syndrome
Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2018Occupant surveys were conducted in 4 office buildings, 2 with traditional non-tinted low-e glass (LeG) and 2 with electrochromic glass (EC). 106 employees working in these buildings volunteered to participate in the study. Results showed that subjective reports of overall ambient lighting conditions were comparable in the buildings.

Electrochromic Effects of Conducting Polymers in Water and Acetonitrile
Molecular Crystals and Liquid Crystals, 1985Abstract Polymer films of several N-substituted pyrroles were deposited on Au electrodes by electrochemical oxidation of the corresponding monomers in CH3 CN electrolyte. Cyclic voltammetry and light reflection measurements were performed in both CH3CN and H2O electrolytes after preparation.

Isotopic Effects in Cation‐Injected Electrochromic Films
Journal of The Electrochemical Society, 1998The elucidation of the role that injected cations play in the creation of electrochromic (EC) color centers in hydrated WO 3 films is presented. The electron and cation contributions to the lattice distortion upon film coloration have been evaluated. The evolution of the fundamental absorption edge and vibrational bands of crystalline hydrate films of

ACS Applied Materials & Interfaces
Dual-band electrochromic (EC) materials are expected to be utilized as building materials for energy saving, but their cycle stability is still an obstacle. Here, two D-A conjugated polymers, PDPPCz36 and PDPPCz27, based on diketopyrrolopyrrole and carbazole linked with different sites, are synthesized.

Effect of temperature on electrochromic device switching voltages
Electrochimica Acta, 1999Abstract Excessive switching voltages in electrochromic devices cause rapid degradation in performance. Optimisation of switching voltages is therefore critical in order to realise the maximum possible device lifetime and to produce a commercially reliable product.
