Product Overview
|
| This ITO Conductive Glass substrate features a precision-deposited indium tin oxide transparent conductive coating on a 0.4 mm glass base, achieving a stable 7-10 Ohm square resistance 0.4mm specification suitable for demanding optoelectronic research applications. The high-transparency conductive oxide layer provides exceptional electrical conductivity combined with optical clarity, making it an ideal photocatalytic electrode substrate for photoelectrochemical water splitting, organic pollutant degradation studies, and dye-sensitized solar cell fabrication. Extensively utilized in university laboratories across China, Singapore, and Hong Kong for advanced research in electromagnetic shielding, biosensing, and thin-film device prototyping, this substrate supports custom resistance specifications ranging from 1 Ω to 10 kΩ with base thicknesses from 0.05 mm to 10 mm. Proper ultrasonic organic solvent cleaning protocol—employing sequential toluene, acetone, ethanol, and deionized water sonication—is essential prior to use to remove production and transport-related surface contamination, ensuring reproducible experimental outcomes and optimal electrode performance. |

Key Features & Advantages
|
- High Optical Transparency with Low Sheet Resistance: The indium tin oxide coating delivers simultaneous visible-spectrum transparency exceeding 85% and electrical sheet resistance in the 7–10 Ω/sq range, enabling dual-function electrode and optical window applications in photoelectrochemical cells, displays, and biosensing platforms.
- Broad Substrate Material Compatibility: Available on standard soda-lime glass, high-purity quartz for UV-transmissive applications, single-crystal sapphire for high-temperature epitaxial growth, and K9 optical glass for precision optical experiments, accommodating diverse experimental wavelength ranges and thermal budgets.
- Wide Custom Resistance Spectrum: Custom sheet resistance spanning six orders of magnitude from 1 Ω to 10 kΩ enables precise impedance matching for specific device architectures, from low-resistance current-collecting electrodes to high-resistance anti-static shielding and field-effect sensor gate electrodes.
- Validated Ultrasonic Organic Solvent Cleaning Protocol: The sequential toluene-acetone-ethanol-deionized water ultrasonic cleaning methodology effectively removes production-derived organic residues, particulates, and adsorbed hydrocarbons that compromise electrode performance, with anhydrous ethanol preservation ensuring contamination-free long-term storage of cleaned substrates.

APPLICATION SCOPE: Extensively deployed as a transparent electrode substrate in mobile phone touchscreens, PDA displays, calculators, and electronic watches. Functions as a photocatalytic working electrode for TiO₂ and WO₃-based photoelectrochemical cells in solar hydrogen production and organic pollutant degradation research. Serves as a transparent current collector in dye-sensitized and perovskite solar cell architectures. Provides EMI shielding for sensitive electronic instrumentation. Utilized as a bioelectrode substrate for electrochemical biosensing and cell culture electrical stimulation experiments. Adopted by university research laboratories in mainland China, Singapore, Hong Kong, and internationally for materials science, surface chemistry, and optoelectronic device prototyping. Available in both ITO and FTO (fluorine-doped tin oxide) variants for elevated-temperature applications requiring enhanced thermal stability.
PACKAGING: Each ITO conductive glass substrate is interleaved with cleanroom-grade lint-free separation film and packaged in a rigid, shock-absorbing container to prevent mechanical damage and particulate contamination during transit. Standard 0.4 mm thickness with 7–10 Ω/sq resistance available from stock; custom resistance (1 Ω–10 kΩ), thickness (0.05 mm–10 mm), and substrate material (glass, quartz, sapphire, K9) configurations manufactured to order. Due to the susceptibility of ITO surfaces to organic contamination during manufacturing, packaging, and transport, mandatory ultrasonic organic solvent cleaning per the specified protocol is required prior to use in all experimental workflows.
IMPORTANT NOTICE: ITO/FTO conductive glass surfaces accumulate dust, grease, and organic contaminants during production, packaging, and transport. Cleaning is mandatory before use. The validated sequential ultrasonic cleaning protocol is as follows: (1) Toluene immersion with sonication for 10–20 minutes to dissolve non-water-soluble grease and oils—toluene exhibits the strongest degreasing capability among common organic solvents; (2) Acetone immersion with sonication for 10–15 minutes to remove residual toluene and remaining organic residues, as toluene is miscible with acetone; (3) Ethanol immersion with sonication for 10–20 minutes to dissolve residual acetone, as acetone is miscible with ethanol; (4) Deionized water rinsing with sonication for 20–30 minutes to remove ethanol, as ethanol is miscible with water in all proportions. For long-term storage, transfer cleaned substrates into anhydrous ethanol and retrieve as needed. Avoid direct handling of the ITO-coated surface with bare fingers; use cleanroom-compatible tweezers gripping only the substrate edges to prevent recontamination.
