(a) Optical image of typical TiO₂ samples placed at different distances from the separation between the two heating zones in the furnace. For the study we considered just the samples between 5 and 6 cm, with a golden appearance. (b) and (c) SEM image for TiO₂/Si and TiO₂/FLG/Si, respectively, both synthesized 6 cm away from the middle of the furnace.
