A very large decrease in the Stokes shift in CdSe nanoparticle (NP) photoluminescence is seen from hybrid materials in which the NPs are attached to single-walled carbon nanotubes after pyridine treatment relative to unbound NPs capped by pyridine. This is observed particularly for very small NPs, for hybrids composed of core-only and core-shell NPs, and for hybrids made with bundles of mixture...

Semiconducting metal oxide and conducting polymers based nanostructures possess unique morphological, optical and structural properties for the important applications in emerging technologies. On the other hand, the semiconducting nanocomposites offer the possibilities to control the properties by varying the composition of the materials and the related parameters such as morphology and an inte...

Networks of single-walled carbon nanotubes (SWNTs) can be processed from solution and have excellent mechanical properties. They are highly flexible and stretchable. Depending on the type of nanotubes (semiconducting or metallic) they can be used as replacements for metal or transparent conductive oxide electrodes or as semiconducting layers for field-effect transistors (FETs) with high carrier...

the nano sized tio2 and zno are the most active photocatalysts.  methylene blue was used as a reference molecule for the photocatalytic degradation. the tio2 and zno can totally remove methylene blue dye. the effect of various process parameters like initial concentration, contact time, dose of catalyst and ph on the extent of removal of dye by photocatalysis in presence of tio2 and zno was stu...

Selective fluorination of organic semiconducting molecules is proposed as a means to achieving enhanced hole mobility. Naphthalene is examined here as a root molecular system with fluorination performed at various sites. Our quantum chemical calculations show that selective fluorination can enhance attractive intermolecular interactions while reducing charge trapping. Those observations suggest...

Recent progress in the synthesis and deterministic assembly of advanced classes of single crystalline inorganic semiconductor nanomaterial establishes a foundation for high-performance electronics on bendable, and even elastomeric, substrates. The results allow for classes of systems with capabilities that cannot be reproduced using conventional wafer-based technologies. Specifically, electroni...

Conductometric semiconducting metal oxide gas sensors have been widely used and investigated in the detection of gases. Investigations have indicated that the gas sensing process is strongly related to surface reactions, so one of the important parameters of gas sensors, the sensitivity of the metal oxide based materials, will change with the factors influencing the surface reactions, such as c...

Three dimensional (3D) elastic hybrid networks built from interconnected nano- and microstructure building units, in the form of semiconducting-carbonaceous materials, are potential candidates for advanced technological applications. However, fabrication of these 3D hybrid networks by simple and versatile methods is a challenging task due to the involvement of complex and multiple synthesis pro...
