Electrochromic (EC) properties of sputtered Ni oxide films have been examined in 1 M KCl+H 2 SO 4 acidic aqueous solutions with H 2 SO 4 concentrations of 0-50 mM. EC coloration efficiency comparable to that in alkaline electrolytes was obtained in a

In this study a copolymer poly(styrene-co-allyl-alcohol), [–CH2CH(C6H5)–]x[–CH2CH–(CH2OH)–]y has been employed as a novel template in a sol–gel synthesis process to direct the formation of mesoporous tungsten oxide. The copolymer, due to

Mesoporous vanadium oxide thin films have been deposited electrochemically from a water/ethanol solution of vanadyl sulfate and a nonionic polymer surfactant. Aggregates of the polymer surfactant serve as templates that result in the formation of a m

We report on the microstructural changes of amorphous V 2 O 5 films with lithium intercalation. The Raman spectra of as-deposited films show two broad peaks around at 520 and 650 cm −1 , due to the stretching modes of the V 3 –O and V 2 –O bond

Electrochromic (EC) devices fabricated with liquid or polymeric gel electrolyte are often less durable than those constructed with inorganic solid-state electrolyte. Long-term degradation of the ion insertion layer (with extensive cycling) by the liq

A detailed systematic study of the tungsten oxide thin films has been carried out using WO 3 films after they were annealed at progressively increasing temperatures ranging from 350°C to 450°C in oxygen environments. The structural properties of th

Standard and mesoporous sol–gel tungsten oxide thin films were prepared by a spin-coating technique from an ethanolic solution of tungsten hexachloride. A block copolymer (BASFk Pluronic p123) was employed as a template to generate the mesoporous s

We report the effects of electrochromic coloration on the Raman spectra of sputtered a-MoO3 films. The Raman spectra of as-deposited films show two strong peaks at 828 and 951 cm−1 due to vibrations of the OMo6+O and Mo6+O bonds, respectiv

The gasochromic mechanism in amorphous tungsten oxide films has been investigated using Raman scattering measurements and optical cycling tests. The Raman spectra of as-deposited films show two strong peaks at 770 and 950 cm 1 due to vibrations of th
