Influence of Ag doping on structural, morphological, and optical characteristics of sol-gel spin-coated TiO thin films.

Pure and Ag-doped Titanium dioxide (TiO) thin films have been synthesized via the sol-gel spin coating method, and their structural, morphological, and optical properties have been investigated. X-ray diffraction analysis verifies that the polycrystalline anatase TiO phase is retained up to 2 % Ag doping. However, lattice expansion and grain refinement down to 25.
