Abstract

Aerosol pyrolysis (AP) was used to prepare thin films of titanium dioxide on various substrates. The films were characterized by SEM, SIMS, XRD, and thickness measurements, and by photoelectrochemical response before and after annealing in various ambients. Pinhole-free anatase films of thickness up to 1000nm were prepared. Incident photon to current efficiencies (IPCEs) of up to 20% at 365nm were obtained for thick films under depletion conditions, in aqueous electrolytes.
