Abstract: A novel method was devised to synthesis an inverted titania crystal on a substrate. At first, a film of surfactant sodium dodecylsulfate (SDS) polystyrene spherical particles was grown on a substrate using Colvin method. Surfactant sodium dodecylsulfate (SDS) stabilizes polystyrene particles and induces necking between the polystyrene particles. Next, the film was dropped inside a Falcon tube that half-filled with a solution comprising Titanium Isopropoxide (TiPT) or Titanium ethoxide (TEOT) diluted with anhydrous ethanol. Then, the Falcon tube was rotated in a centrifuge machine set at 1200-3600 rpm. After 30 minutes the film was removed from the tube and placed inside an anti-static plastic container. The film was stored inside the container for at least 6 hours. This was repeated many times depending on the dilution of the precursor solution (the more diluted the precursor the more the repetition) to fill up voids among the polystyrene colloidal particles.
