Room temperature sensor is a research hot for metal–oxide gas sensors. However, electron activation is a bottleneck to improve sensitivity for room temperature sensors. Here, an ultraviolet (UV)-activated gas sensor based on a single-sheet porous single-crystalline (PSC) zinc oxide (ZnO) sheet has been fabricated instead of heating activation, which works at room temperature. The PSC ZnO nanosheets...
In this paper, the growth, optical and structural characterization of ZnO nanoporous structures on plastic substrate using low temperature aqueous chemical growth technique. ZnO nanoporous structures were fabricated using hydrolysis process by reacting zinc acetate dehydrate with pure ethanol. The ZnO particle size and morphology was observed by X-ray diffraction (XRD), atomic force measurement (AFM),...
In this paper, ZnO nanomaterials with high effective specific surface area have been prepared and subsequently deposited on the SAW transducer as sensitive layer, finally the responses of the sensor to different ethanol gas concentrations were investigated at room temperature.
In this paper, we describe a low temperature, solution-based synthesis uniform ZnO nanorods with a gram scale, and their ethanol gas sensor property. The morphological, structural and optical properties of the as-prepared nanorods were investigated by means of transmission electron microscopy, high-resolution transmission electron microscopy, X-ray diffraction and photoluminescence. The results showed...
ZnO tetrapods with a cross-sectional size of about 200-1000 nm were synthesized via an oxidation reaction technique. The sensors based on ZnO tetrapods and platinum impregnated ZnO tetrapods were fabricated and investigated for ethanol sensing properties. The gas sensing properties of the sensors were investigated for ethanol concentration of 50-1000 ppm at different operating temperatures. It was...
ZnO nanoparticles were synthesized by flame spray pyrolysis (FSP) using zinc naphthenate as a precursor dissolved in toluene/acetonitrile (80/20 vol%). The particle properties were analyzed by XRD, BET, and HR-TEM. The sensing films were produced by mixing the particles into an organic paste composed of terpineol and ethyl cellulose as the vehicle binder and were fabricated by doctor-blade technique...
The third order nonlinear optical properties of ZnO nanorods and ZnO nanoparticles in water, N,N-dimethyll formaide and ethanol were comparatively investigated by using Z-scan technique under nanosecond pulses at 532 nm. Experimental results show that the structure of ZnO nanocomposites has effect on their third order nonlinear optical performances, and the third order nonlinear optical properties...
This paper describes an application of quartz tuning forks (QTF) coated with nanocrystalline ZnO films used as relative humidity sensors. The nanocrystalline ZnO thin films were deposited on the QTF by sol-gel method. The film was characterized by X-Ray Diffraction (XRD) and Atomic Force Microscope (AFM) to obtain the information on the structural and morphological properties. And the humidity sensitivity...
Nano-sized ZnO crystals with catalytic, electrical, optoelectronic, and photochemical properties have been considered as an important candidate in both fundamental research and practical studies. However, controllable synthesis of ZnO in morphology and size with a simple method under mild conditions still represents a challenge. We proved that ZnO nanostructures, including particles and nanorods,...
