Abstract.

Nanocrystalline Ni 8 wt% doped TiO2 powder was synthesized by mechanical alloying. Microstructural and photo-spectrometiric analysis showed that the Ni added up to 8 wt% was dissolved into the rutile TiO2 matrix. The absorption threshold of the Ni doped powder shifted from 380 to 500 into the visible light region. (480–500 nm)
