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...
متن کاملInfluence of Co and Fe substitution on optical and structural properties of zinc oxide thin films
Zn0.97TM0.03O (TM = Co, Fe) thin films were deposited onto glass substrates by the sol–gel method and the effects of transition metals substitution on structural and optical properties of ZnO films were investigated. The X-ray diffraction patterns revealed that the films have wurtzite structure. Optical transmittance of the films was recorded in the range of 200 -800 nm wave length and the band...
متن کاملStudies on sol-gel dip-coated nanostructured ZnO thin films
Nanostructured ZnO thin films were prepared by sol-gel dip coating technique. Zinc acetate and ammonium hydroxide were used as precursors and ethanol was as solvent. Ammonium hydroxide (NH4OH) solution was added drop-wise under vigorous stirring to obtain the sol-gel of different pH (varying from 6.9 to 7.2). ZnO thin films were obtained by dipping the glass substrates for few seconds and then ...
متن کاملSynthesis and Characterization of Zn-doped and un-doped SnO2 nanostructures for PV Applications
Tin oxide nanostructures, un-doped and Zn-doped, have been prepared by conventional sol-gel technique. Research grade tin chloride (SnCl2.2H2O) and zinc acetate (Zn(O2C2H3)2) were used as tin and zinc sources. Ethylene glycol and alcohol were used as solvents under different synthesis conditions. Transparent un-doped and Zn-doped SnO2 sol was prepared after continuous stirring and refluxing at ...
متن کاملEffects of Cobalt Doping on Optical Properties of ZnO Thin Films Deposited by Sol–Gel Spin Coating Technique
Cobalt (Co) doped Zinc Oxide (ZnO) thin films, containing different amountof Cobalt nanoparticles as the Co doping source, deposited by the sol–gel spin coatingmethod onto glass via annealing temperature at 400˚C, have been investigated by opticalcharacterization method. The effect of Co incorporation on the surface morphology wasclearly observed from scanning electron microscopy (SEM) images. ...
