Oxide Semiconductor Sensitizer

Ruthenium Dye 470 sensitizes efficiently wide band-gap oxide semiconductors, like titanium dioxide, up to a wavelength of 600 nm.

The maximal absorption coefficient is ~ 21′500 /mol.cm at 465 nm and pH = 14. At pH = 1, the absorption coefficient is ~20′000 /mol.cm at 468 nm wavelength. Ruthenium Dye 470 remains attached to titanium dioxide in acidic aqueous solutions up to pH = 3.

This sensitizer is suited for photochemical water splitting experiments, e.g. together with a tungsten oxide counter-electrode.
