Gold Substrates

Mesoporous silica thin films were fabricated on gold substrates with a sol-gel method including a cationic surfactant. The interface of gold and silica thin films was fixed with a mercaptosilane. The surface roughness of the thin films and their grain sizes of silica were both increased with the elimination of the cationic surfactant and polyethylene glycol (PEG) modification on its surface. The surface reaction, adsorption of bovine serum albumin (BSA), was monitored with surface plasmon resonance (SPR). Although the adsorption amount of BSA at 1 mg/mL were 7.9 ng/cm2 on the mesoporous silica, the PEG modification can completely desorb BSA. The mesoporous silica thin films on gold substrates fabricated will be a good platform for analyzing surface reaction.

Electrical And Optical Properties

In this study, antimony-doped tin oxide (ATO) thin films were fabricated by the sol–gel dip coating process on glass substrates. After the deposition process, the films were treated by Argon–plasma (Ar-400 Watt). The effect of argon–plasma treatments on the electrical and optical properties of ATO thin films was then investigated as a function of the plasma treatment time. It was found that Ar–plasma treatment increased the electrical conductivity of ATO films, but it decreased the optical transmission of ATO thin films.
