چکیده

Tin oxide (SnO2) thin films are widely used by solgel method. One of the most important factors that influence the sensitivities of sensing material is its structural properties especially surface morphology. In this work, we present preparation and characterization of undoped and antimony-doped tin oxide (Sb: SnO2) thin film nanostructures for gas sensing applications. The films were characterized by XRD, SEM and AFM. The SEM and AFM images of films showed a very smooth surface morphology with nanostructure grain size in the range of 40 to 45 nm. Sensing sensitivity of Sb: SnO2 films are much higher than undoped films.

Synthesis of Zinc Oxide Nanostructured Thin Film by Sol- Gel Method and Evaluation of Gas Sensing Properties

Ethanol (C2H6O) sensitivity of zinc oxide (ZnO) thin film has been studied in present work. Semiconductor thin films of zinc oxide (ZnO) were deposited onto alkali-free glass substrates by the sol–gel method and dip-coating technique. The ZnO sol was synthesized by dissolving zinc acetate dehydrate in ethanol, and then adding Tetra ethanol-amine.  The as-coated films were preheated at 150 ºC fo...

UV Light Activation of TiO2-Doped SnO2 Thick Film for Sensing Ethanol at Room Temperature

TiO2-doped SnO2 nanopowder is synthesized via a sol-gel method and characterized by atomic force microscopy and X-ray diffraction. Using this nanopowder, we have fabricated a novel semiconductor gas sensor that is sensitive to UV light illumination. We find that gas-sensing properties of TiO2-doped SnO2 sensor can be enhanced significantly under the exposure of UV light. The sensor exhibits a h...

Preparation of macroporous SnO2 films using PMMA microspheres and their sensing properties to NOx and H2

Macroporous SnO2 (mp-SnO2(P-n); P means polymethylmethacrylate (PMMA) and n = diameter of PMMA microsphere) thick film gas sensors were fabricated by a modified sol-gel method by employing PMMA microspheres (n = 800, 400, 250 and 150 nm) as a template and SnCl2 as a tin source. Morphology of mp-SnO2 films was markedly dependent on the SnCl2 concentration and the diameter of PMMA microspheres. E...

Micro Semiconductor CO Sensors Based on Indium-Doped Tin Dioxide Nanocrystalline Powders

The precursors of SnO2 or In2O3/SnO2 nanocrystlline powders have been prepared by the sol-precipitation method. The precursors were calcined at different temperatures to prepare SnO2 or In2O3/SnO2 nanocrystalline powders with different particle sizes. The nanocrystallites were examined by differential thermal analysis (DTA), X-ray diffraction (XRD) and transmission electron microscopy (TEM). An...
