“…Thus, the roughness seems to be dependent on the annealing temperature value. Our results and observations agree with the work of Mechiakh et al [24] who reported that the RMS value was found to increase from 0.617 to 3.713 nm for sol-gel TiO 2 thin films annealed at 350 and 450 °C, respectively; and that the increase in the roughness is due to the increase in the grain size. Similarly, Urlacher et al [25] found, in the case of sol-gel ZrO 2 waveguides, that the amorphous film exhibits a smoother surface than the crystallized one, and the RMS varies from 0.2 to 2.1 nm, when increasing temperature from 300 up to 600 °C.…”

TiO 2 thin films were synthesized by sol-gel process: titanium tetraisopropoxide (TTIP) was dissolved in isopropanol, and then hydrolyzed by adding a water/isopropanol mixture with a controlled hydrolysis ratio. The as prepared sol was deposited by "dip-coating" on a glass substrate with a controlled withdrawal speed. The obtained films were annealed at 350 and 500 °C (2 h). The morphological properties of the prepared films were analyzed by Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM). The optical waveguiding properties of TiO 2 films were investigated for both annealing temperature using m-lines spectroscopy. The refractive indices and the film thickness were determined from the measured effective indices. The results show that the synthesized planar waveguides are multimodes and demonstrate low propagation losses of 0.5 and 0.8 dB/cm for annealing temperature 350 and 500 °C, respectively.

“…For all diagrams, the peaks marked by dashed line are due to the contribution from the ITO substrate. Also, in the range 15-35° a broad hump appears, probably due to an amorphous glass contribution[27,28].Fig.1aillustrates the XRD patterns of the TiO 2 thin films annealed at 450°C obtained by sol-gel method and deposited by spincoating onto ITO glass substrate. From this figure, we can observe two main peaks at 25.6° and 48.7° corresponding respectively to the reflection planes of (101) and (200), respectively.…”

“…The sol-gel process is a soft chemistry method whereby the precursors are often in a form of colloidal solution that ultimately 'transforms' into an extensive network of either discrete or continuously-linked molecules. In our case, it was selected due to its inherently simple and safe characteristics in which solid-state synthesis could be accomplished at relatively low temperatures [17,25].…”

A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT2 AbstractNew cobalt-based metal oxide thin films (M x Co y O z with M = Mn, Cu, Ni) have been deposited on commercial aluminium and glass substrates using sol-gel dip-coating method.The as-deposited films were characterized by a wide range of complementary techniques including X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), X-ray photoelectron spectroscopy (XPS), Spectrophotometry and Nanoindentation techniques. A light absorption study for coatings on glass substrates within a wavelength range of 300-1100 nm was also conducted. Topographical and morphological investigations showed the presence of nano-sized, grain-like particles in the copper-cobalt oxide coatings, which consequently had the roughest surface among the three coatings. All coatings on glass substrate exhibited higher absorption of ultraviolet (UV) light compared to visible light, while coatings on aluminium substrate generally had low reflectance (< 50 %) of UV light, moderate reflectance (< 80 %) of visible light and high reflectance (up to 100 %) of infrared light. Implications of optical properties as a function of film thickness controlled by dip-heating cycles were discussed. The elastic modulus (E) and hardness (H) of thin film samples compared with standalone commercial aluminium substrate were also measured.
