A solid state system having the configuration WO3/Ormolyte/CeO2-TiO2 has been assembled. The solid electrolyte, an organically modified electrolyte (ormolyte), was prepared with different [O]/[Li] ratios. The transmittance variation of this system during a potentiostatic step from -0.7 V to 0.8 V was about 35% at 550 nm.447-451engelectrochromic devicesWO3CeO2-TiO2hybrid materials-ormolyteArtigo10.1023/A:1008751630771WOS:000166544900083Acesso restrito
