However, whilst protection against UV may be maintained at smaller particle sizes, the rate at which hydroxyl radicals are generated increases, due to the inherent photo-activity of these materials. This paper shows that photoactivity can be reduced (by over an order of magnitude) by doping the material with small amounts metallic cations ( | | ISBN: | 0-9767985-1-4 |
