Nano-rutile-titania has been synthesized via a sol-gel route using titanium tetra n-butoxide as the precursor and ethyl alcohol as the solvent at a low temperature of 80 • C. When synthesized with HCl as the catalyst, the powders crystallized without calcination, while the materials prepared using a
Films of thickness $3 mm containing nanosized metal particles of iron, nickel and copper respectively were grown on a Corning glass slide using a sol-gel technique. The particle sizes had values in the range 6.8 to 20.1 nm. Optical absorption characteristics of different specimens were studied over
