AZO Coated Glass

AZO Coated Glass Specifications and Details

The Aluminium doped Zinc oxide (AZO) coated glass is a transparent conductive oxide (TCO) over a soda-lime glass substrate. It has manufactured by using target sputtering method. It is a transparent conductive glass substrate with transmittance greater than 81%. The AZO coated glass is a single side coated slides, whereas the other side is insulated. It is not easy to identify the conductive side with bare eyes. It is suggested to a used multimeter or four-probe method to confirm the coated side.

AZO coating serves as a cost-effective and environmentally friendly alternative to traditional conductive coatings such as ITO, making it ideal for large-scale and research-based applications. The material exhibits low sheet resistance, high visible light transmittance, and good thermal stability, allowing it to perform efficiently even under elevated temperatures.

Manufactured using precision sputtering techniques, AZO coated glass ensures uniform coating thickness and consistent electrical properties across the surface. Its single-side conductive layer makes it suitable for applications where controlled conductivity and insulation are required.

Dimensions & other details

The AZO coating or layer thickness is 800 - 850nm, and the resistivity is around 10 ohms/sq.cm. The surface of the substrate is quite smooth, but the surface roughness (RMS) is 2nm. The maximum size produced is 304.8mm x 304.8mm in a 3.2mm plate thickness. Our standard sizes are 25mm x 25mm, 50mm x 25mm, 50mm x 50mm, 75mm x 25mm, and 100mm x 100mm. The uniformity of resistance and Haze is less than 10%. It is beneficial for heating applications since its maximum operating temperature is 600 °C.

The AZO coated glass is less popular as compared to ITO and FTO glass, but it is the best economical option for many applications. It is mainly utilized in the LCD's, RF-EMI shielding, solar cell fabrication, optoelectronic devices, photovoltaics, etc.

Applications

In modern electronic and optoelectronic devices, it is used as a transparent conductive layer, combining high optical transparency with good electrical conductivity. It is commonly found in OLEDs, LCDs, touchscreens, sensors, and flat-panel displays, where both clear visibility and efficient electrical performance are required. On touchscreen devices, these coatings help the screen detect touch input while maintaining a clear, smooth display. In energy applications, it is used as a front conductive layer in thin-film, crystalline silicon, perovskite, and tandem solar cells. Its transparent nature allows sunlight to pass through easily, while the conductive layer efficiently carries an electrical charge.

Its radiation resistance and stability make it suitable for aerospace and satellite devices. It is also used in smart and electrochromic windows, where it helps regulate light transmission and control heat, improving building energy efficiency and indoor comfort. In RF-EMI shielding applications, it reduces electromagnetic interference while maintaining transparency. It is used in gas sensors, biosensors, surface acoustic wave devices, and piezoelectric devices because of its conductive and surface-sensitive properties.

It is commonly used as a conductive base and electrode surfaces in laboratory work, semiconductor manufacturing, and micro- and nano-scale fabrication. Its smooth surface, transparency, and conductivity make it useful for thin-film coating, nanoscale structures, and research on advanced materials.

How to Use?

• Check the glass carefully for scratches, chipped edges, or coating marks before using.
• Always place the coated side facing upward before starting fabrication or assembly work.
• Keep the work area clean and free from dust to prevent contamination on the glass surface.
• Use lint-free gloves and hold the glass only by its edges while handling it.
• Move the glass sheets with vacuum lifters, plastic tweezers, or other soft-contact tools to avoid damage.
• Blow away loose dust with filtered air or nitrogen before starting the process.
• Clean the glass only when needed, using approved solvents and lint-free cloths or wipes.
• Make sure the glass surface is fully dry before any coating, printing, or deposition work begins.
• Apply light and even pressure while fitting the glass into frames, holders, or fixtures.
• Perform cutting and shaping operations from the uncoated side whenever possible.
• Remove glass particles and debris immediately after cutting or drilling operations.
• Store unused sheets vertically using cushioned separators between each sheet.
• Maintain low humidity and stable room temperature during storage and operation.

Safety Measures

• Wear safety goggles, cut-resistant gloves, a lab coat, and safety shoes while handling the glass.
• Handle the glass carefully and avoid dropping, bending, or putting uneven pressure on it.
• Do not place heavy tools or equipment on the coated glass surface.
• Protect the material from sudden temperature changes, extreme heat, or rapid cooling.
• Use proper ventilation while working with solvents, etchants, or cleaning chemicals.
• Unless approved, strong acids, alkalis, or abrasive compounds should not be used on the coating surface.
• Keep food, liquids, and unnecessary materials away from the processing area.
• Remove damaged or contaminated glass sheets from usable materials as soon as they are identified.
• Use proper collection tools when handling broken glass.
• Throw broken glass and chemical waste only into the marked industrial waste containers.
• Clean the work area after processing to avoid particle contamination during later operations.
• Follow all laboratory or facility safety rules during fabrication, transportation, and storage work.
