Notes:
Well-crystallized nanopolycrystalline thin films of cubic strontium titanate, SrTiO3, havebeen prepared on the TiNi-deposited Ni substrate in Sr(OH)2 aqueous solutions at temperaturesbetween 130 and 200°C under saturated vapor pressures. The microstructure and morphology of thefilms were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Thephotoelectrochemical properties of SrTiO3 thin films on TiNi-deposited Ni substrate wereinvestigated on a three-electrode assembly. The grain sizes increased from 30 nm to 300 nm and therelative crystal intensity in XRD pattern increased with the reaction temperature. Its photocurrentincreasesdfirst with the grain size, then decreased. When the grain size of the film is about 200 nm,the photocurrent is highest
