Figure 2From: Fe effect on the optical properties of TiO2:Fe2O3 nanostructured composites supported on SiO2 microsphere assembliesA SiO 2 microsphere layer coated with TiO 2 :Fe 2 O 3 . (a) Formation of ‘micro-shavings’ (×2500) dispersed on the glass substrate, (b) lateral view at ×25,000 of the SiO2 spheres on glass substrate, and (c) lateral view at ×65,000 of the SiO2 spheres on glass substrate.Back to article page
