We have used silicon and glass as substrate for gold and platinum thin films deposition. The film thickness are between 40 and 440 nm for gold and between 26 and 220 nm for platinum. We have analyzed these samples by scanning tunneling microscopy and by X ray diffraction. The crystallographic and morphological grain sizes are discussed.

Gold nanoparticle dimers assembled on the surface of CdS QD thin films served as nano-antennas to mediate the distance-dependent plasmon enhanced electrochemiluminescence of QDs.

Self-assembled monolayers and bulk films of thioanilines, polymerized on gold and platinum surfaces, have been characterized and compared to bulk polyaniline (PANI) films. In a previous study [Kuwabata; et al. Langmuir 1999, 15, 6807-6812], only one redox couple was observed in the cyclic voltammetric profile of a polymerized monolayer of thioaniline on gold, in contrast to the known profiles o...

Polyelectrolyte multilayer films adsorbed on gold surfaces were studied by combined ellipsometric and electrochemical methods. Multilayers were composed of "synthetic" (poly(4-styrenesulfonic acid) ammonium salt (PSS) and poly(allylamine hydrochloride) (PAH) (PSS/PAH)) and "semi-natural" (carboxymethyl cellulose (CMC) and chitosan (CHI) (CMC/CHI)) polyelectrolytes. It was found that only PSS/PA...

Covalent attachment of a microporous polymer network (MPN) on a gold surface is presented. A functional bromophenyl-based self-assembled monolayer (SAM) formed on the gold surface acts as co-monomer in the polymerisation of the MPN yielding homogeneous and robust coatings. Covalent binding of the films to the electrode is confirmed by SEIRAS measurements.

A simple and versatile approach was developed to generate hierarchical assemblies of ultra-small gold nanocluster thin films using the combination of galvanic reaction and a block copolymer coordinated with gold complex. Variation of the temperature allows effective control over the optical response of these stimuli-responsive organic-nanocluster hybrid structures.

Convective assembly at high volume fractions was used to assemble gold nanoparticles into structured porous films templated by colloidal crystals. These gold nanofilms have hierarchical porosity and were proven to be stable and efficient substrates for surface-enhanced Raman spectroscopy (SERS). The control over the film structure allowed optimization of their performance for potential sensor a...

Direct lyotropic liquid crystalline templating has been successfully applied to produce nanostructured IV–VI semiconductor PbTe thin films by electrodeposition both on gold and n-type (100) silicon substrates. The PbTe films were characterized by transmission electron microscopy, X-ray diffraction and polarized optical microscopy and the results show that the films have a regular hexagonal nano...
