S-doped powders having an anatase phase (ST-01) and a
rutile phase (NS-51) under UV or visible light irradiation. (a) under UV light
irradiation without a cutoff filter, (b) under UV light irradiation at
wavelengths longer than 350 nm, (c) under visible light irradiation at
wavelengths longer than 390 nm.
