“…Despite the apparent limitations and uncertainties associated with adventitious carbon referencing, it is the most convenient and commonly applied technique that were widely used in the published papers. [11][12][13] Photoluminescence measurement was performed by excitation from a 325 nm He-Cd laser at room temperature. Both ZnO nanorods and ZnS powder were used as the standards.…”

Heterostructured ZnO-ZnS core-shell nanotube arrays with the diameters of 50-80 nm and lengths up to 1 m were synthesized by a two-step chemical reaction. First, the ZnO layer was grown by atomic-layer deposition. It was found that the preferred growth orientation was strongly dependent on the substrate temperature. After sulfuration conversion from arrayed ZnO nanorods, the ZnS-ZnO composite arrays can be successfully prepared, as evidenced from transmission electron microscopy. This confirms that the ZnO-ZnS core-shell nanotube-arrayed structure has been fabricated. X-ray photoelectron spectroscopy analysis indicates that the binding energy of S 2p is the same as that of bulk single-crystal ZnS and that the Zn 2p 3/2 peak is shifted about 0.5 eV due to the formation of Zn-S bonds. Photoluminescence shows the relative-intensity ratio of ultraviolet emission ͑I UV ͒ to deep-level emission ͑I DLE ͒ for ZnO / ZnS core-shell nanotubes can be enhanced to be nine times that of original ZnO nanotubes.

“…A methodology to produce hydroxy-terminated siloxane-anchored SAMs and multilayers, which takes advantage of the photolysis of a nitratefunctionalized SAM for the formation of surface hydroxy groups without any reagents, was later reported. [141] This photoconversion allowed the photopatterning of films and subsequent construction of multilayers.…”

Engineering Silicon Oxide Surfaces Using Self‐Assembled Monolayers

Although a molecular monolayer is only a few nanometers thick it can completely change the properties of a surface. Molecular monolayers can be readily prepared using the Langmuir-Blodgett methodology or by chemisorption on metal and oxide surfaces. This Review focuses on the use of chemisorbed self-assembled monolayers (SAMs) as a platform for the functionalization of silicon oxide surfaces. The controlled organization of molecules and molecular assemblies on silicon oxide will have a prominent place in "bottom-up" nanofabrication, which could revolutionize fields such as nanoelectronics and biotechnology in the near future. In recent years, self-assembled monolayers on silicon oxide have reached a high level of sophistication and have been combined with various lithographic patterning methods to develop new nanofabrication protocols and biological arrays. Nanoscale control over surface properties is of paramount importance to advance from 2D patterning to 3D fabrication.

“…Die Photolyse einer Nitrat-funktionalisierten SAM zur hydroxyterminierten SAM lieferte SAMs und Multischichten mit hydroxyterminierten Siloxanverankerungen, ohne dass weitere Reagentien erforderlich waren. [141] Diese Photokonversion machte es möglich, die Filme vor dem Aufbau der Multischicht photolithographisch zu strukturieren.…”

Gestaltung der Siliciumoxidoberfläche durch selbstorganisierte Monoschichten

Nur wenige Nanometer dicke molekulare Monoschichten können die Eigenschaften von Oberflächen vollkommen verändern. Die Herstellung dieser molekularen Monoschichten kann leicht durch die Langmuir‐Blodgett‐Methode oder durch chemische Adsorption (Chemisorption) an Metall‐ und Oxidoberflächen erfolgen. Dieser Aufsatz konzentriert sich auf chemisorbierte selbstorganisierte Monoschichten (SAMs) als Plattformen für die Funktionalisierung von Siliciumoxidoberflächen. Die Organisation von Molekülen und molekularen Aufbauten auf Siliciumoxid wird in der “Bottom‐Up”‐Nanofabrikation einen außerordentlichen Platz einnehmen und könnte Gebiete wie die Nanoelektronik und die Biotechnologie in naher Zukunft revolutionieren. In den letzten Jahren wurden selbstorganisierte Monoschichten auf Siliciumoxid so weit entwickelt und mit verschiedenen lithographischen Methoden kombiniert, dass neue Nanofabrikationsstrategien und biologische Arrays entwickelt werden können. Will man Fortschritte auf dem Weg von der Bildung zweidimensionaler Muster hin zur dreidimensionalen Fabrikation erzielen, ist die Kontrolle von Oberflächeneigenschaften im Nanometerbereich von größter Bedeutung.
