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.

The ITO surface is susceptible to organic contamination from manufacturing, packaging, and transport. Mandatory ultrasonic organic solvent cleaning must be performed prior to use, and cleaned substrates should be stored in anhydrous ethanol to prevent recontamination.

Surface Contamination Sensitivity: Dust, grease, and organic residues accumulate on the ITO coating during production and handling, requiring mandatory cleaning before experimental use.
Ultrasonic Cleaning Requirement: A sequential ultrasonic cleaning protocol using toluene, acetone, ethanol, and deionized water is necessary to remove all organic contaminants.
Storage in Anhydrous Ethanol: After cleaning, substrates must be stored in anhydrous ethanol to maintain a contamination-free surface until retrieval.
Handling Precautions: Avoid contact with the ITO-coated surface using bare fingers; use cleanroom-compatible tweezers gripping only the substrate edges.

HowTo

Sequential ultrasonic cleaning in toluene, acetone, ethanol, and deionized water removes organic residues and particulates from the ITO surface. This protocol ensures reproducible electrode performance and optimal experimental outcomes.

FAQ

How does the 7–10 Ω/sq sheet resistance of ITO conductive glass affect its suitability for photoelectrochemical water splitting versus touchscreen applications?

The 7–10 Ω/sq range provides a balance between conductivity and optical transparency for dual-function electrode and window applications. For photoelectrochemical cells, lower resistance (e.g., 1 Ω) may be preferred for efficient current collection, while touchscreens benefit from the standard 7–10 Ω/sq for adequate conductivity with visible-spectrum transparency exceeding 85%. Custom resistance from 1 Ω to 10 kΩ is available for impedance matching.

Why is the sequential ultrasonic cleaning protocol with toluene, acetone, ethanol, and deionized water mandatory before using ITO conductive glass substrates?

ITO surfaces accumulate dust, grease, and organic contaminants during production, packaging, and transport. The sequential protocol ensures complete removal: toluene dissolves non-water-soluble oils, acetone removes residual toluene, ethanol removes acetone, and deionized water removes ethanol. Skipping steps can leave residues that compromise electrode performance and experimental reproducibility.

What is the recommended long-term storage method for cleaned ITO conductive glass substrates to prevent recontamination?

After cleaning, store substrates in anhydrous ethanol to maintain a contamination-free environment. Avoid direct handling of the ITO-coated surface; use cleanroom-compatible tweezers gripping only the edges. This prevents recontamination from skin oils and particulates, ensuring optimal performance in subsequent experiments.
