Polyethylene glycol-directed SnO2 nanowires for enhanced gas-sensing properties.

SnO(2) nanowires with lengths in the tens of micrometres range have been synthesized on a large scale via a facile polyethylene glycol-directed method at ambient temperature followed by a suitable thermal treatment of the precursor nanowires. The morphology of the precursor of the SnO(2) nanowires is tunable by changing the concentration of either SnCl(2) or polyethylene glycol. After calcinati...

Fully transparent thin-film transistor devices based on SnO2 nanowires.

We report on studies of field-effect transistor (FET) and transparent thin-film transistor (TFT) devices based on lightly Ta-doped SnO2 nano-wires. The nanowire-based devices exhibit uniform characteristics with average field-effect mobilities exceeding 100 cm2/V x s. Prototype nano-wire-based TFT (NW-TFT) devices on glass substrates showed excellent optical transparency and transistor performa...

Sensitive and Selective Ammonia Gas Sensor Based on Molecularly Modified SnO2 †

The development of selective and cheap metal oxide gas sensor at ambient temperature is still a challenging idea. In this study, SnO2 surface functionalization was performed in order to obtain sensitive and selective gas sensor operated at ambient temperature. 3-aminopropyltriethoxysilane (APTES) was used as an intermediate step, followed by functionalization with molecules having acyl chloride...

An olive-shaped SnO2 nanocrystal-based low concentration H2S gas sensor with high sensitivity and selectivity.

Olive-shaped SnO2 nanocrystals were synthesized successfully via a facile hydrothermal route, using tin dichloride hydrate, oxalic acid dihydrate and polyvinylpyrrolidone as reaction precursors, and showed great potential in the large-scale preparation of SnO2 nanocrystals. The prepared SnO2 nanocrystals were characterized using XRD, XPS, SEM, TEM and HRTEM, and showed well-defined olive-shaped...

Chemical gas sensors based on nanowires

Chemical gas sensors based on nanowires can find a wide range of applications in clinical assaying, environmental emission control, explosive detection, agricultural storage and shipping, and workplace hazard monitoring. Sensors in the forms of nanowires are expected to have significantly enhanced performance due to high surfacevolume ratio and quasi-one-dimensional confinement in nanowires. In...
