Spray Pyrolysis Deposited ZnO Nanopebbles as Room Temperature Ammonia Sensor
A nanopebble-textured ZnO film made by high-temperature spray pyrolysis selectively senses ammonia at room temperature down to 1 ppm.
Thin Films Research
Publications producing literal thin-film material forms — by spray pyrolysis, sputter deposition, or sol-gel dip coating — regardless of the specific deposition route, useful for browsing across every thin-film technique at once.
Racetrack Effect on the Dissimilar Sensing Response of ZnO Thin Film: An Anisotropy of Isotropy
A single sputter-deposited ZnO film shows the 'racetrack effect' creates a real spatial gradient in crystallite size, carrier mobility, and gas-sensing response across one nominally uniform substrate.
Thickness Dependent Room Temperature Sensing Properties of Spray Pyrolysis Deposited Nanostructured ZnO Thin Films
Substrate temperature controls ZnO film thickness and grain size in this zinc-nitrate-precursor study, with the thinnest, highest-resistance film giving the strongest acetaldehyde response.
Modulation of ZnO Film Thickness and Formation of Water-Hyacinth Nanostructure
Switching the spray-pyrolysis precursor solvent between water and ethanol tunes ZnO film thickness from 875 down to 150 nm, producing a distinctive water-hyacinth nanostructure along the way.
A Simple and Novel Room Temperature Ethanolamine ZnO Nanosensor
Spray-pyrolysis ZnO films made with different water-ethanol precursor solvents show the ethanol-only film selectively detects ethanolamine at room temperature, with a stable response over 30 days.
Fluorine Doped ZnO Thin Film as Acetaldehyde Sensor
Fluorine doping shrinks ZnO crystallite size and increases micro-strain, and a 4 wt% fluorine-doped film gives the strongest, most selective room-temperature acetaldehyde response.
Nano Ceria as Xylene Sensor: Role of Cerium Precursor
Precursor chemistry alone tunes spray-pyrolysis CeO2 sensing performance: the acetate-derived film forms nanosheets and gives the fastest, strongest room-temperature xylene response.
Oxygen Sensing Characteristics of Milled Metal Oxide Materials
Silica and titanium dioxide powders made by stirred bead milling were pressed into pellets and separately deposited as thin films to compare their room-temperature oxygen response.
Sol-Gel Dip Coated Pure and Fe-Doped Nanostructured ZnO Thin Films
Pure and iron-doped ZnO thin films are grown by sol-gel dip coating, a low-temperature alternative to spray pyrolysis, to study how iron doping shapes the resulting nanostructure.
Solvent Volume Driven ZnO Nanopetals Thin Films: Spray Pyrolysis
Precursor volume alone steers spray-pyrolysis ZnO toward either better conductivity or better gas sensing, with a distinctive nanopetal morphology forming at 30 mL.
