ITO Coated Quartz Glass

Description and Specification ITO Coated Quartz Glass

ITO Coated Quartz Glass is a specialized material. It has the unique properties of quartz glass and the functionalities of an Indium Tin Oxide (ITO) coating. Quartz glass is composed of highly pure silica (SiO₂ ≥ 99.9%) extracted from sources like quartzites and rock crystals. It is known for its exceptional resistance to water and strong acids (except hydrofluoric acid). Quartz glass has a very high melting point and low thermal expansion. These characteristics make it highly resistant to thermal shock and suitable for applications that involve rapid temperature changes. Quartz glass can transmit ultraviolet and infrared light, with the degree of transmittance influenced by the additives used during manufacturing.

When coated with a thin layer of ITO, quartz glass gains transparent conductive properties. These properties enhance its optical transparency while maintaining its basic durability. ITO Coated Quartz Glass is widely used in advanced technological applications like touchscreens, photovoltaics, and optoelectronic devices, where a combination of transparency, electrical conductivity, and thermal stability is required.

This coated glass is well-suited for applications such as micro-structuring and patterning. All transparent conductive oxide coatings have a few nanometers thick protective silicon dioxide (SiO₂) layer. This layer is a protective barrier, positioning the ITO film in direct contact with a high-purity quartz layer while isolating it from the glass substrate. This design improves the functionality of LCDs by preventing the leak of alkali oxides from the soda-lime glass into the liquid crystals. As the SiO₂ layer blends in well with the coating process, it greatly enhances the performance of ITO Coated Glass without raising prices. Its unique characteristic of blocking alkali ions is useful for various electronic applications.

Applications of ITO Coated Quartz Glass

ITO Quartz Glass Slide is widely used in different fields because it combines good electrical conductivity and optical clarity. Here are some of its applications:

• Touch Screens ITO slides act as electrodes in touch screen devices. Its clear appearance allows bright visuals, while its conductive nature helps detect touches.
• LCDs and OLEDs ITO slide is transparent conductive layers in LCDs (liquid crystal displays) and OLEDs. This setup enables the display to work effectively by allowing electricity to flow and light to pass through.
• Biosensors The slide is used in biosensors to identify biological interactions. The clear conductive layer supports various analysis methods, including measuring fluorescence and absorbance.
• Chemical Sensors ITO slide is also found in chemical sensors that monitor chemical reactions. The ITO coating allows for electrical measurements and assists in optical detection techniques.
• Solar Cells It functions as transparent conductive electrodes in thin-film solar cells. This setup lets light reach the solar cell’s active layers while conducting electric current.
• Microscopy Slides In laboratory research, ITO glass slide is utilized as microscope slides: its clarity and conductivity benefit imaging and various analytical methods, such as fluorescence microscopy.
• Material Research Its unique combination of transparency and conductivity makes it an excellent substrate for depositing thin films, making it ideal for studying new materials and coatings.
• Electrochemical Cells The slide is used as electrodes in electrochemical experiments. The conductive layer allows for accurate electrochemical measurements and reactions.
• Smart Glass ITO coated slide is a key in creating electrochromic or “smart” glass, which alters its transparency in response to applied electrical signals.
• Surface Science ITO glass slide is useful in surface science research to explore surface interactions and properties, taking advantage of its unique characteristics.

How to use ITO Coated Quartz Glass ?

• ITO coated slide is packaged in specialized protective sheets to ensure it remains undamaged and uncontaminated during transport and storage.
• Before utilizing an ITO-coated slide, it is advisable to clean it with isopropyl alcohol, a solvent that preserves the integrity of the ITO layer.
• Under no circumstances should alkali solutions be used to clean the slides. While dilute sodium hydroxide solutions are often employed for patterning ITO, it is unsuitable for cleaning.
• The recommended method involves using high-quality, lint-free cotton wipes or cotton swabs soaked in isopropyl alcohol to clean the slides effectively.
• It is crucial to avoid using acidic substances, even mild acids, as these will cause irreversible damage to the ITO coating.
• Store ITO coated glass in a dry, dust-free, and dark environment, maintaining humidity below 60% and temperatures between 5°C and 25°C.
• Ensure the slides remain in its original packaging and is used within six months of storage.
• Wear clean, lint-free gloves when handling ITO coated glass and hold the slides by its edges.
• Prevent contact or friction between multiple slides to minimize the risk of scratching or static buildup.

Safety Guidelines

• Wear protective equipment (PPE) such as cut-resistant gloves, safety goggles, and long-sleeved clothing to safeguard against sharp edges and prevent cuts and abrasions while handling ITO Coated Quartz Glass.
• To control nuisance dust and airborne particles, perform cutting activities in designated areas equipped with local exhaust ventilation (LEV).
• Use specialized cutting tools for quartz glass to minimize splintering and breakage.
• Store glass sheets or components on padded, stable racks to prevent accidental tipping or breakage.
• Label storage areas clearly for easy identification and minimize mishandling risk.
• Provide training for workers on safe handling practices, hazard identification, and response to incidents involving glass breakage.
• Keep first-aid kits accessible and ensure all personnel are trained to address injuries promptly.
