Sol-gel TiO2-0.25MnO has been obtained using a colloidal solution. The ther
mal transformation behavior of the fresh xerogel was followed by simultaneo
us thermal analysis (STA) and powder X-ray diffraction (XRD). Sol-gel coati
ngs were deposited by dipping and the successive dense films were optically
characterized using W-VIS-NIR spectrophotometry. (C) 2000 Elsevier Science
